you could just remove "english" from the search (or at most also "japanese" and "chinese" if you haven't blacklisted any language). Honestly I don't even know if textless is supposed to have works that include both a dialogue version and a textless version, the current description "The lack of language or story to read in a given work." isn't clear enough you also should keep in mind that tags have been proposed for works with more versions, so that could also be another solution without the need of creating a tag that's almost the same as "textless" if you really care about this, I think the best way would be to propose a new description for "textless", just so that a discussion can be opened in a more meaningful way
