Search results don't match the query
Each search result more or less corresponds to the user's query. Search results are arranged from more relevant to less relevant.
Yandex tries to make the search results page diverse and take into account various interpretations of the query. This is why results contain exact matches to your query, as well as related documents that are still helpful. For example, if you look up a product, you'll also see reviews and store addresses, and if you search for [Jaguar], you'll get a description of the car as well as the animal.
Queries can also be location-dependent and location-independent. In the former case, sites that are related to the search region are preferred. In the latter case, site and search region don't affect search results.
