These settings let you enable stemming (morphological analysis) of the selected languages.
Stemming of a language is the basis for the text search in YouTrack. When you enable the morphological analysis of a language, YouTrack finds not only the exact original word, but also its word forms. For example, when you search for the word "board", YouTrack finds issues that contain the words "board", "boards", "boarding", and so on. Each time an issue is created or updated in YouTrack, the issue attributes that store strings of text (the summary, description, and comments) are indexed in each language that is enabled on this page.
Text indexing is automatically enabled for all default languages. This means that stemming is enabled for all issue attributes that store strings of text in any of the languages that are provided out-of-the-box in YouTrack. YouTrack provides additional support for other languages. This means that you can enable text indexing and optimize your search queries if you write your issues in a language other than the language that is displayed on the user interface. For example, the language setting for your YouTrack server is English, but you create issues in Danish..
