Sticker hints

You can set your own keywords for stickers. For this, send any message to vk.me/stickerskeywords and follow the instructions (for now only available in Russian).

On iOS, first disable hints and then enable them again. You can do this in the My stickers section of the stickers store: vk.com/stickers.
Your search for returned no results.
Try using other keywords, e.g.: "delete profile", "create chat".
Check your request for misprints.
