Open.by

Open.by is the Belarussian internet catalogue and internet portal that presents the wide spectrum of information and informative services to the user, in the number of that social networks, news, weather and catalogue of web-sites. A portal disposes the line of search, through that there is possibility to carry out a search, that allows Open.by to consider a valuable search engine.

Basic task of search engine of Open.by - to give it possibility of complete text search in the internet of information on the Belarussian web-sites. In him the all Belarussian are collected the internet resources with BY by domens and greater part not with BY by domens. An information retrieval can come true by sight, on a catalogue or automatically, on keywords, with the use of boolean operations.

The special system of rating provides the primary show of the most popular and visited servers. Information renovates every day.

Searching system Open.by has an own catalogue of web-sites. A directory structure is built on principle of the known catalogue of Yahoo! Choosing an interesting division, an user gets access to contained in him theme to the resources that is sorted first of all on rating, after on the index of quoting and in the last turn on the name.

Searching machine of Open.by is the first searching system in Belarus. In times of the existence a few domens were replaced, and set to the work as catalogue and search engine of the Belarussian web-sites 09.open.by in December, 1998. The official opening for the public use took place on March, 30, 1999. 

In a catalogue a search was conducted on descriptions of web-sites, on the base of announcements and by system of netnewss of USENET. 

Web was also used - spider, that in the automatic mode saved the pages of web-sites on a searching server. On these pages a complete text search was produced. It was suggested to set the meter of visits on a web-site on that rating of web-sites was formed. 

The first serious processing of the system was conducted in 2000-2001. 

Depth of deflation of web-sites and additionally began to pump out dynamic pages. 

For an acceleration and improvement of релевантности search began to use an index  file, for realization of fulltext search on complete content of web-sites. Possibility of creation of difficult queries appeared with inlaid and logic "NOT", "OR". 

Rating is finished off, determination of the Belarussian users is added.

The automatic searching device of the new Belarussian web-sites appeared. 

Domen of search engine of Open.by was replaced on All.by of October, 18, 2000. 

In the middle of 2002 a rendering-engine (searching mechanism) was cardinally changed, the technology first used in Google was fixed in basis of that.com, it substantially influenced on an increase релевантности "query-answer". First in Belarus a search became possible taking into account morphology of Russian. The index of quoting, rating statistics, was added for a month, viewing of local copy of web-sites became possible, the chart of ranging of pages became better taking into account the index of quoting of web-sites.

At the end of 2002 the system became part of portal of Open.a by domen was replaced on poisk.open.by. For this time to the catalogue new divisions were added, possibility of the extended search, and also search, appeared on commodities on the trade ground of shop.by and context advertisement of commodities in the results of search. 

In 2003 the mechanism of codeindexing of pages was improved in a search engine, and also the system allowing maximally quickly to process the queries of users even in a clock peak is created. Codeindexing of documents was added in the format of doc, xls, rtf, pdf, swf. 

In the middle of 2004 amount of web-sites registered 8000 exceeded in the system. From them about 3000 participate in rating. The number of proindex pages attained 3000000. 

March, 2005, was marked beginning of collaboration with Yandex. An aim is expansion of the offered services and improvement of quality of search. Now the results of search on the Belarussian web-sites are formed on the basis of data of search in All.by and in Yandex.

Presently searching system Open.by develops dynamically, attracting everything new and new users and extending the catalogue of resources.

Jayde

Jayde - known enough and popular in the countries of Western Europe and North America searching catalogue of web-sites. For the proprietors of web-sites registration in the searching catalogue of Jayde is very important, first of all for advancement in other searching systems. The most popular search engines of the world strongly emphasize web-sites being in the searching catalogue of Jayde. 

A searching catalogue of web-sites of Jayde is this plenty presently enough of resources the quantity of that exceeds three with a half millions. The project of catalogue of Jayde was open in May, 1999 the collective of programmers of Michegan university (USA). At sponsorship of sponsors he began headily to develop and collect popularity among users.

To get in the searching catalogue of Jayde - presently it is one of the first tasks for proprietors and developers of web-sites. On the face of it, a process seems simple enough and accessible for all, but passing indexation is in strength to not all resources.

Not looking on all brought difficulties over with indexation, a searching catalogue of Jayde still is a success among users in the different corners of Earth.

To the lacks of searching catalogue it is necessary to take her oriented to the resources in English language, web-sites on other languages in a catalogue will not join.

ImHalal

ImHalal - first on spaces of the internet islam search engine. A search engine was worked out by the Arabic programmer Reza Sardeh at sponsorship of sheiks of Oman and start for work in the internet at the end of September, 2009.

ImHalal differs from other search engines that does not give out results with content that conflicts with the postulates of islam. This search engine can distinguish the results of search settled for moslems from forbidden. 

The searching system ImHalal works on the basis of the three-ball system, estimating web-sites for the purpose their prohibition by islam dogmas, and, in case if the found web-sites have a high level of forbidenness for moslems or disparity to the norms of islam, suggests to set other terms of search or specify other searching phrases. 

So, for example, if an user will make an effort find materials of pornographic character, then the system will give out a report that this content is forbidden by the norms of islam and can not be given out by a search engine in demand of user. 

The searching machine of the searching system ImHalal is based on searching technologies of Inctomi and on principle of work very reminds her. The feature of this searching system consists in the set filters that sift from in the internet undesirable and incongruous to the norms of islam information.

Besides English, a web-site can find materials on other languages, in particular, on Arabic, Russian, French, Spanish and on the row of other languages and dialects.

In opinion of creator of service Reza Sardeh, new searching service of ImHalal will give an opportunity to the moslems to barrier itself and near from web-sites content of that falls short of to the laws of sheriat.

The new searching system is already approved by the moslems of the practically whole world and begins to be a success among moslem users.

AltaVista

AltaVista the most known American searching system, that uses popularity among the users of the USA, Canada and some countries of Europe. AltaVista was worked out and start in a network at the beginning of December, 1995 at support of the most powerful at that time calculable server of DEC Alpha. On the period of the appearance AltaVista was the most rapid searching system that could process millions of searching queries in a day.

The important innovation of search engine of AltaVista was including of search of human language. Users could print a searching phrase or question and get an intellectual answer.

In the first approaching the worked out by a corporation AltaVista Technology AltaVista was sold Digital Equipment Corporation. The known now searching system substantially improved by the specialists of DEC became accessible to the users in November, 1995. In 1998 the searching system back was bought by a corporation Compaq, that spent quite a bit time and forces on the search of possibilities to do a profitable project from AltaVista. Thus the address of the searching system remained former.

And a set in the address line of AltaVista resulted in a hit on the web-site of company AltaVista Technology. As a result, the fame of the searching system resulted in the enormous inflow of visitors on a web-site AltaVista Technology and loss of potential users the searching system. In the total, a domen back of search engine of AltaVista was bought Compaq after 3,35 million dollars in August, 1998. In spite of it, Compaq so not succeeded to be got income from the searching system.

Therefore in June, 1999 the negotiations of Compaq and corporation CMGI began about forming of strategic network alliance, within the framework of that AltaVista was sold CMGI. on it was August, 19, 1999 announced acquisition by a corporation CMGI at Compaq of 83 percents of actions of AltaVista.

In February 2003 AltaVista was bought Overture Services, Inc., that in July 2003 was purchased Yahoo!. From May 2011 AltaVista passed to searching technology of Yahoo! at the use of her catalogues and searching machine.

Gave one of first AltaVista to the searching machine the short name, created a simple title page interface without an advertisement and extraneous references.

Now official headquarters of this searching system is in city Palo Alto, that is located in neighbourhood Santa Klara, state California, USA.

QIP

QIP - lately becoming very well the known to all Russian portal worked out by a provider ICQ on Russian the internet space in 2003. As well as very much services have alike portals and social networks on the web-site, in the number of that e-mail, collection of news, informative selections on the real estate, music, life of stars et cetera. To the number of services of QIP, except the given services in ICQ, that are basic, an information retrieval belongs in the internet. 

First shortly we will consider a question, from where this service happened on the whole and searching system QIP in particular. This search engine is not alike service popular universal messenjer QIP Infium, and by his direct copy. Getting on the official web-site of the Russian analogue of ICQ, the user of the Internet gets possibility not only to begin to swing the known software product but also chance to take up many other virtual businesses. 

On the whole the interface of portal (just like this it is already possible bravely to name QIP) reminds Mail.ru, such his early version. Here is a place, as we marked already, to the news, service of acquaintances, looking for a job, horoscope, viewing of photo galleries and other great deal. 

Presently to talk about some revolutionary technologies in the field of search QIP is not outside, as this searching system uses algorithms and searching database that is made the searching machine of Yandex. But in case with the search engine of QIP, except the taken information from the catalogue of Yandex, the searching machine of QIP indexes some pages of web-sites, increasing the volume of treat searching queries. 

In account of analysts and from data the internet of questioning, today the searching system QIP processes 0,6 percents of all queries in Runet. Moreover, it is an index slowly, but confidently creeps upwards. 

In opinion of experts, height the Internet of audience, carrying out a search in a network through QIP, first of all, related to that a portal prescribes the search in popular web-browsers "by default" in moment when messenjer is set. Many users, noticing possible deception (absence is in the browser of traditional Yandex), here restore this omission in tuning.

But I am and such, who continues to use QIP, especially as the results of delivery are fully tolerable (as it was already marked higher, QIP uses the algorithms of Yandex, complementing them in an insignificant measure by the data). And such people, as practice shows, every day becomes all anymore, that makes happy the proprietors of this perspective searching system.

Baidu

Baidu is the Chinese searching system that is a leader among the Chinese searching systems and searching systems of countries of south-east Asia. On the amount of the processed queries of pages of resources a searching web-site Baidu occupies the third place in the world (more than three with a half milliards of treat pages, that makes more than 5 percents from a general amount in a global search. 

The Japanese version of Baidu, that forced out Bing from Japanese the space internet literally for 2-3, started in 2002.

Baidu also has the on-line-encyclopaedia - Encyclopaedia of Baidu, that on the amount of addresses to her passed users Chinese Wikipedia.

There are more than 800 million, more than 90 million photos and images and about 15 million mediafiles web pages in the searching catalogue of Baidu.

In 2010 the basic web-site of the searching system Baidu was exposed to the attack of hackers from the "Iranian cybernetic army". Malefactors changed DNS of record and redirected a traffic on other web-site, what Baidu of irreparable damage caused.

In April, 2006 by the search engine of Baidu it was declared about the start of alternative project - Baidupedia. Already in three weeks she passed Chinese Wikipedia on the number of reasons. 

Presently the encyclopaedia of Baidu contains more than 5 million reasons (there are no more than 4 millions in English Wikipedia). The corrections brought in Baidupedia become visible not immediately, and pass through moderators and, probably, censors. At the same time, in Baidupedia there is the article about Wikipedia in that Wikipedia is described in the neutrally-positive key.

Long time in her there was information about her blocking in China, and references were even given to the mirrors of Wikipedia, on that it was possible to call on her main page. After a while references to the mirrors were cleaned, was left only reference to the official main page on that, however, from China to call to Wikipedia it was impossible to the removal of blocking. An interface is done by maximally comfortable for users from China. Visual style of enciklopedia is simple. References and bold type are supported in the articles only.

Comments are located внизу every page. Among the similar functions of Wikipedia a web-site supports editing, commentation and publication of reasons, and also function of history of changes in the article.

Presently the programmers of Baidu are develop the Russian-language version of search engine, that on the plans of guidance of the searching system must create competition to the leading Russian search engines, in particular Yandex, Nigma, Rambler, and some in general it is planned to force out from electronic space of Russia.

lanl.arXiv

lanl.arXiv is the American searching system that behaves to the class of the scientific searching systems. The system was worked out by the programmers of Los Alamos of national laboratory of nuclear researches in 2006 for systematization of scientific information and scientific electronic publications. Developments on creation of this searching system were conducted two with small years and made off in May, 2006 presentation of the searching system of lanl.arXiv, the name of that forms from the name of university that supervised and supported the process of her creation.

In itself this searching system is Los Alamos archive of electronic scientific publications and developments in different areas. It is collection of copies of reasons on physics, mathematics, nonlinear dynamics, computer science. 

By the aim of creation of the searching system of lanl.arXiv her developers had creation of searching catalogue for systematization and free exchange by scientific information. 

Ученные, that are the authors of scientific developments and reasons place them here to the official publication, and sometimes and quite without the aim of further publications. 

lanl.arXiv disposes a searching machine that systematizes entering her base information on thematic divisions. For this purpose the author of publication brings before indexation a searching machine the article in the database of the searching system, forming the catalogue of information the same.

The system is a success in the scientific circles of the USA and after his limits. Many West-european scientists use the database of lanl.arXiv for the scientific publications. Similarly large popularity this searching system uses in the countries of former Soviet Union and South-east Asia.

DMOZ

DMOZ is the most known European searching catalogue, or Open Catalogue of web-sites, as he itself names, or ODP (Open Directory Project) - prestige among all searching catalogues in the world. 

Registration of web-site in the catalogue of DMOZ is fundamentally important, especially when the question is about advancement in the searching systems. In particular, the leading search engines of the world strongly emphasize web-sites being in DMOZ catalogue.

There is even such concept, as general searching catalogue that is not that another, as complete copy of open catalogue, and on that there is a separate search in the search engines of Yahoo!, Yandex and Bing.

A catalogue of web-sites of DMOZ is vast collection of resurs, open for addition of web-site visitors. This project functions and moves up due to the collective of editors from different corners Earth that work voluntarily, estimating web-sites and adding them to the directory of ODP partitions. If the editor of division DMOZ approved a web-site, then he is added in accordance with the subjects of division that is divided by the great number of shallow categories.

A web-site needs to be added only to the division: for example, "program catalogue of films" - in the category of films or programs, et cetera. So-called catalogue of Yahoo! works on the basis of Open Catalogue of DMOZ.

However in the catalogue of Yahoo! web-sites are represented some по-иному, what in ODP. In a difference from many catalogues in that web-sites are situated without the account of their meaningfulness, resources in the catalogue of web-sites of Yahoo! assorted in order of importance them for users. It is determined Yahoo! on the basis of technology of PageRank, or PR, many other factors are here taken into account. At first blush to know quality of web-site and whether it is needed to visit him, the green strake of value PR stands opposite every reference. Thus, the best from the point of view of Yahoo!

Web-sites are shown on the first positions, but not hide among the great number of another web- resources.

To get in the catalogue of web-sites of DMOZ is a dream of many web-masters. And although registration of web-site in the catalogue of DMOZ is maximum simple, adding a web-site is succeeded only to units. Why? The point is that the editors of project are conduct very hard, but just politics of estimation of quality of the resource added to collection. We will put baldly: swingeing majority of Internet-projects does not have not the least chance to get in the catalogue of DMOZ.

Certainly, many their proprietors it seems to that their web-site answers the requirements of open catalogue to quality, but such errors rarely are sincere. At first blush on a main page to the editor is clear that web-master examines people as improvised material for realization of the plans, and to such web-sites a road in the open catalogue of DMOZ is closed. However, and to the look to the web-site not often reaches after reading that is given as the "name and description".

It is very important to pass registration in the catalogue of Open Directory from the first time. The point is that if a request on adding to Open Catalogue will be declined, then on her will do a mark: "Web-site on befits on reasons", and very unsoon an user will succeed to obtain, that a request was considered repeatedly. Therefore before to begin registration of web-site in the catalogue of DMOZ, it is vitally necessary to check all his pages for quality. 

In a word, how to estimate the web-site and educe defects, it is described. Since all of it will be removed, possible to pass directly to registration in a catalogue - to give a request on adding of web-site to DMOZ.

For the general taking on catalogues: "to register", but in catalogues it is accepted to write "Add Site" or "Submit URL". A registration statement in ODP consists of three fundamentally important moments. To add a web-site to the catalogue of DMOZ, it is necessary and enough, as they say mathematicians, to do the following:

It is correct to choose a division a web-site can be added in that.

Seriously to pick up words and fill by them a line the "Name of web-site".

Correctly to make description to the web-site, answering the requirements of ODP.

To enter kods done for protecting from automatic registrations.

To push the button "To Add a web-site to Open Catalogue".

First three points of registration of web-site in DMOZ catalogue quite not so simple, as seem at first blush! To suffice it to say that the incorrect choice of division, superfluous word in heading or even absence of point, at the end of description can forever recover a way to Your web-site in this prestige in the world catalogue of web-sites. And such happens with most web-sites at addition: they do not come even to that they were looked by the editor of division.

Clear that it is a theme for the separate article in that we will take apart, as correct to choose a division and fill a registration statement in open catalog DMOZ.

an open catalogue is extremely useful to advancement of web-site

to aim to get in DMOZ it is necessary it is necessary all methods

quality web-sites are accepted in Open Directory only

to drive the own web-site to the norm very unsimply

drafting of request on addition determines success

Not looking on all brought difficulties over with registration, a searching catalogue of DMOZ still is a success among users and developers of web-sites, similarly very widely used by other most known search engines of the world for determination of results of search.

Witch

Witch is the German searching system, that was worked out by programmers from Munich within the framework of the general project sent to systematization of the German resources of the internet. The aim of project was to create the catalogue of resources and pages for the searching system that would satisfy the queries of the German users on an one or another information retrieval.

The prosecutions of creation of this searching system began in January, 2002 at financing the internet of corporation Beerenberg under the direction of Rune Gart (on information of administration of the searching system he and now is the technical director of this structure). Presentation of the searching system Witch took place on July, 15, 2003 after three months of testing and tests on the internet space of Germany.

The searching system Witch has quickly renovating an index with a strong enough searching machine capable qualitatively to investigate resources during time. And it in turn allows then to find necessary information that is inquired in a search any user, on the set of searching phrases or words.

The about 8 million pages of resources are presently investigational the searching machine of Witch on the English and German languages, that can qualitatively and at high level to satisfy the queries of the German users. 

Much to our regret, Witch offers the small choice of variants of search presently, but on this defect moderators and administration of the searching system work constantly. 

Creators and proprietors of Witch are right to be proud of the created searching system, first of all because on the conducted questioning of the German users of the internet he is used by 7 percents from the incurrence of polled, that is a seventh index on Germany.

To the lacks of search engine of Witch it is necessary to take a limit orientation of search only on resources in German language or on resources with subjects, touching Germany. And therefore popularity of the searching system takes place only on territory of Germany, Austria and partly Switzerland. But it fully reasonably because this searching system has the brightly expressed territorial direction and geotarting.

Zubr

Zubr is the Belarussian searching catalogue worked out and inculcated on the internet space of Belorussia at the end of 2008 state the internet by a company Beltraf for resources and users of Belorussia or oriented to the internet space of Belorussia. 

The system was worked out by the group of the Belarussian programmers on basis and principles of already existing in North America and Europe of searching thematic catalogues. 

The searching machine of Zubr works so that indexes the pages of resources that is brought in by their owners on the ratified form in the catalogue of this search engine. Pages of resources not accessioned by the searching machine of Zubr not indexed and in the results of search not represented. 

To the features of search engine of Zubr it is possible to take on by the Russian-language search, searchability on other languages, namely German, English, French and Spanish.

By the end of 2011 the about million pages of the studied and proindex resources were counted in the database of searching catalogue of Zubr.

Except services of search of resources in the internet, this searching system gives possibility to become familiar on the pages of the web-site with the latest news in area of politics, state, business and internet to the users, similarly with the useful articles on different themes and spheres of everyday life. Services of translation of text information are similarly given with the use of transcription of ten anchorwomen of the world languages. 

Zubr gives to the user complete enough to information in area of ecashs and electronic commerce, where the special attention is spared to such anchorwomen to the electronic payment systems, as EasyPay and WebMoney, exchange, input and conclusion of facilities from these systems, to the purchase of different commodities in the internet shops and to the receipt of services in a network for ecashs in these systems.

Quite possible, that in the near future, the searching system Zubr will grow into the valuable internet portal of Belorussia. And while to the lacks of the searching system Zubr it is possible to take her limit nature only the internet by space of Belorussia.

Clusty

Clusty is the new enough searching system worked out by the group of engineers of programmers of the American company Vivisimo Inc. jointly with specialists and research workers of Carnegie Mellon University's.

Company Vivisimo Inc., that is specialized on software and systems of search development in the internet, started the бета-версию of the worked out search engine of Clusty of September, 30, 2004. 

A search engine was developed during four years and was adopted so by virtue of one of the features are groupments of results of search on different categories, id est clusterizations. Collecting, for example, the name of city in a query, on the left it will be possible to see specifying categories: hotels, business, tourism, history et cetera. For different queries categories are determined from the results of search, and according to their list will be also different. In addition, every web-site can be looked over straight on a page with the results of search in a small window (frame-е).

Vivisimo Inc. hoped to press Bing (36 percents) and Yahoo (29 percents) at the market of the searching systems of countries of South and North America. To take the internet space was planned due to an innovation in-process searching machine that by radical character differed from the searching machines of leading search engines of America. It was succeeded partly, but not in such scale, as be pre-arranged. Reason consisted of conservatism of users that did not begin to change to the habits to use the old and known already searching systems.

It was planned that the search engine of Clusty in перове time would be able to index approximately from 5 to 10 million web pages, that notedly yielded to the results of ведучих search engines. 

Modernizing a search machine, Clusty notedly promoted this result to 2 milliards of pages on the state on the end of 2011.

The searching system works so that practically deprived defects, and to her advantages it is necessary to take first of all an operationability at codeindexing of pages of resources. The new page of web-site in English language gets in the base of the system in the flow of 72 hours from the moment of publication, and it excels the indexes of such searching systems notedly, as Bing and Yahoo.

Presently the searching system Clusty develops dynamically. It is planned to adapt the interface of search engine under the language features of some countries of Europe and Asia, to work out the additional base of these resources on the German, French and Russian languages, and similarly to systematize an advertisement campaign on advancement of search engine in the internet space of countries of Eastern Europe and Asia.

Yahoo!

Yahoo - one of the oldest search engines of the internet that uses enormous success with the USA and Canada, and similarly in a number of countries of Europe.

Yahoo was founded in 1994 and registered in city New York, as independent the internet enterprise.

Yahoo has the oldest searching catalogue in the Internet among all known searching systems of countries of America, where editors by hand distribute web-sites on categories. 

However, in October, 2002 Yahoo produced a large change, passing to the use of searching robot for the main results of search. 

To February, 2004 Yahoo used the database of Google. To date Yahoo uses the own technology of search. 

In addition to the excellent results of search on the main page of Yahoo an user can use located higher than searching line of book-mark, to search a picture, results from "YPS" or to use the excellent searching system Yahoo for being of commodities. It is similarly possible to visit the main page of Yahoo Search, where more specialized searching options are offered.

The catalogue of Yahoo continues to function. It is here possible to notice references to the thematic categories of catalogue in the underbody of page of results of search. In transition on references an user gets the list of web-sites that is added by the editors of Yahoo.

In addition, an user can search directly in the catalogue of Yahoo. For this purpose instead of main page of Yahoo the address of page is entered: dir.yahoo.com. Then an user will get references to the thematic categories of catalogue ("Related Directory Categories"), and results from a catalogue ("Directory Results"), that are most relevant to the query by web-sites from all categories of catalogue of Yahoo.

To be plugged in the commercial categories of catalogue of Yahoo, a web-site must pass requiring payment registration and get the consent of editors. Noncommercial web-sites are accepted in the catalogue of Yahoo free of charge. The program of acceptance of web-sites of Yahoo also offers the requiring payment plugging in the page of results of search of the searching system Yahoo. 

Yahoo promises that it will not influence on ranging. The program of search also free of charge gives out the web-sites of noncommercial organizations.

As well as Google, Yahoo offers the requiring payment placing of references to the web-site. They are for sale through Overture. Yahoo purchased Overture Services in October, 2003.

Overture to the end of 2001 GoTo was named. In March, 2003 Overture bought AllTheWeb, and in April of the same year - AltaVista. Now due to acquisition of Overture Yahoo is a proprietor both AllTheWeb and AltaVista.

Technology of AltaVista and AllTheWeb was incorporated with the searching system Inktomi, to create a present searching robot Yahoo. As is generally known, Yahoo bought Inktomi in March, 2003. Therefore results of search in Yahoo will be analogical with the results got in AltaVista and AllTheWeb.

Besides the squeak of Yahoo it is a social network, both MTA and catalogue of different information useful to the user yet and.

Lately Yahoo was adapted to the languages and the internet to space of row of countries of Asia and Eastern Europe, that allows to him it notedly to rise in rating of users.

Meta.ua

Meta.ua is the Ukrainian internet portal that is for users most successful and popular in Ukraine in the field of grant of wide spectrum the internet of services. It, foremost, social network, row of informative and educational portals, giving most different information, news, MTA, on-line translator, there are more than 60 languages of the world in the base of котрого, and much other.

Among services there is a portal of Meta.ua gives to the users and searchability of the necessary Ukrainian resources in the internet.

The internet is a portal of Meta.ua was worked out and registered by an of the same name company at the end of 1999. Gradually with expansion of functions of portal, his administration worked out the system of search in the internet of necessary information. At the beginning for basis of search principle of work of searching machine of Yandex was taken, but with development of portal it was made decision about development of own searching machine that would differ from already existing. 

Since 2005, when the scopes of search broadened notedly, a portal had begun to use for realization of search already the own searching machine, that, as well as planned before, was not alike on principles of work on none of already existent machines, but all and was not deprived defects at first works.

Search engine of Meta.ua on the essence and on principle of work there is meta by the searching system (what his name talks about) and limit inquires the results of search and base of these systems uses that. However, as compared to the row of the alike and analogical searching systems, Meta.ua gives more fast access to necessary to the user of information.

To undeniable advantages of this searching system we take circumstance that a search comes true on keywords and phrases depending on a  resource in the catalogue of the system, id est from the place in rating, made the searching system. Rating of Meta.ua straight depends on the number of visits of resource users, id est, than higher visited and highly sought of web-site, the he higher will be in rating, and consequently and in a search. 

To not sufficiencies of the searching system Meta.ua it is necessary to take her limit nature the internet by space of Ukraine. By the searching machine of Meta.ua is indexed exceptionally web-sites about Ukraine or in Ukrainian language. Other web-sites or pages do not join in the searching rating.

By the end of 2011 in the database of the searching system Meta.ua was more than 2 million pages of resources that were studied and plugged in rating of the system.

Now Meta.ua popular enough portal and search engine among the users of Ukraine, that gives complete enough information, especially in the division of business, technique, science, jurisprudence, industry and agriculture.

WebCrawler

WebCrawler is the new enough American search engine worked out by programmers and the internet by designers in 2002. By an aim given creations of the searching system it was to work out the searching system, that would unite in itself work of two quite different searching machines, belonging Google and Yahoo!.

This search engine started in the Internet after the protracted enough testing lasting a year without small. Such protracted period is explained by plenty of errors that were sufferet on the initial stages of development of search engine of WebCrawler.

Since beginning 2005 year of WebCrawler began to work in the normal mode, the scopes of search of WebCrawler broadened notedly, the searching system had processed the more than six million pages of the resources produced on the different languages of countries of America and Europe.

To basic advantages of the searching system WebCrawler it is possible to take that hybrid two basics of searching machines widespread in America turned out very successful and presently works without considerable errors. Consists the feature of work of searching machine of WebCrawler of that she quickly enough indexes the pages of resources without the additional bringing them in the database of the system, that characteristically for Yahoo!
