Nigma

Nigma - Russian intellectual мета searching system, the first system using the method of clusterization. A project is created at support of two faculties of Moscow State University, and also specialists of the Stanford university. The name "Nigma" originates from the name of one  types of spiders, it was chosen on an association with internet.

In the moment of appearance of Nigma two men participated in a project, namely programmers of Viktor Lavrinenko and Vladimir Chernichov. On November, 2011 more than thirty persons work in a project.

A basic innovation of this search engine is in that he carries out a search on the method of division of information on clusters. This method consists of that on the basis of the entered user query Nigma forms the list of the documents divided into a few great numbers (clusters). An user can specify, in what great number to continue a search, improving the same analogicalness results. An user can eliminate the unnecessary to him great numbers of web-sites also. The list of clusters hatches on the left of list of results.

For every cluster a formative him phrase and amount of documents are specified in a cluster. An user can manage clusters through the special references under the list of clusters.

Search engine of Nigma - it one of the best search engines on spaces of countries of former Soviet Union. In a search engine a function is realized multi search. Nigma contains the own base of resources, but besides it allows to execute a search at once on all most popular searching systems.

Another possibility of this service can be interesting to the schoolchildren and students. Search engine of Nigma offers services of Nigma of mathematician and Nigma chemistry. The first is intended for the rapid decision of simple equalizations and different arithmetic operations, allows the second to work with the formulas of chemical reactions. Searching service of Nigma recognizes more than thousand physical, mathematical constants and units, allowing quickly to execute transformation from one dimension in other.

Service offers to similarly the dispatch of free SMS all leading operators of mobile communication, blogs, mail, dictionaries et cetera, at that a hit on the indicated pages takes place one ads.

For the improvement of quality search it is possible to use the special characters (operators) that will specify to the searching system, that with some words of query it is needed to work as the special character.

When an user executes an ordinary query from a few words, the searching system tries to find, first of all, pages containing most of words from a query. Id est, on the first places pages on that there is a maximal amount of words from a searching phrase will stand in the list of the shown out results.

On the basis of previous queries of users of Nigma the system offers the variants of auto of additions for a searching query. In the improved version the reflection of results of query takes place till a query will be fully entered in the line of search.

The searching system Nigma every day collects all anymore and more admirers and users that use the system. But to the lacks of the system it is necessary to take the use a search engine only to Russian morphology, that does not allow in a sufficient measure to index web-sites, using morphology of other languages.
