Web Crawler
What is YandexSearchShop?
Yandex says this agent downloads product catalogues in YML files at users' request. Such feeds may be stored in paths prohibited to ordinary indexing, which is why the published table says general robots.txt rules are not taken into account. This is a requested catalogue fetch rather than the primary YandexBot search crawler or the separate YandexMarket robot.
