That way, it returns more documents in response to general search queries and more accurate results in response to more specific queries. The search results show a video [snippet](https://yandex.com/support/webmaster/search-results/site-description.html) and links to its hosting sites. The link to the hosting site the video is played from by default is shown first. Yandex chooses a hosting site with a high-quality player and not too many ads as the default one. If the parameters are equal, a hosting site is selected randomly. For more information, see [How do I improve my player's position in a combined video?](https://yandex.com/support/video/en/partners/combined-videos.md) In viewing mode, you can [choose a video hosting site to play a video](https://yandex.com/support/video/en/search-video.md#source). Video hosting owners can post duplicates of the same video. This is done via markup. To learn more, see [How to mark up duplicates](https://yandex.com/support/video/en/partners/open-graph.md#duplicate).
