FIELD: information technology.
SUBSTANCE: plenty of search requests entered into a search system are got in the method of processing search requests. Each search request is processed. The processing includes obtaining a set of lexemes and a set of synonyms, calculating a set of normalized requests based on search requests and lexemes, calculating a set of generalized requests based on normalized requests and synonyms, and compiling an index structure based on a set of logical trees. Each normalized request is associated with the corresponding generalized request. Compiling of the index structure includes computing a set of logical trees. Each logical tree is a general request which is associated with a generalized request.
EFFECT: reduction of calculating resources due to the fact that the problem of combinatorial explosion is resolved when processing long search requests.
