This article covers the creation of the corpus of the Uzbek language and the creation of a search system based on linguistic tags for its effective use. First of all, various linguistic units in the scope of search - word form, lemma, syntactic unit, collocation, phrase and grammatical constructions were analyzed. Also, the interface elements, filters, methods of displaying results and statistical indicators used in the corpus search are described. The article shows the main types of corpus tagging - lexical (POS), morphological, syntactic and semantic tags, and their effect on search capabilities. At the same time, linguistic search methods through n-gram analysis, collocation detection, and regular expression (regex) are widely covered in the corpus. These approaches provide an opportunity to effectively use the corpus of the Uzbek language in the fields of scientific research, language teaching and automatic language processing.
