The conformity assessment of the query options to the original search query is calculated. Text fragments are searched in the corpus of electronic texts that satisfy the query for the query options. The search includes a semantic-syntactic analysis of the found text fragments. The conformity assessment of the lexical values of words in the found fragments to the lexical values of words of the original query option is calculated. The found text fragments are ranked according to the calculated conformity assessment.
