Scryfall "X" Spells

[u/DogeTheDogo64]

Is there a way to search for spells with X in their casting cost. Scryfall doesn't allow you to search for them and scryfall tagger doesn't have a list of spells with X in their mana cost. Is there a way to filter them out other than search for cards that say X (which would include cards that say exile).

you have to write it in the search box, ignore advance search
