search does not search in emoji, if text is search

[LuckyTurtleDev]

All stickerpack I does use have only emojis deposited.
If I did search a emoji it all packs with the emoji are showed.

But if I enter as example "disappointed" in the search, no sticker packs are showed. The search should also displayed sticker with emoji 😞.
Tipping emojis is usually not supported by the keyboard, especially on the pc.
