All tiddlers with no tags except

[paulgilbert2000]

ok sorry found my answer here

Filter needed: All tiddlers with specific tag but that have no other tags

Hi everyone, I need another filter: This is for spotting tiddlers that all have the same specific tag, but I need to spot where I didn’t add a secondary tag. I need a filter that does the following: List all tiddlers with tag [[Foo foo]] but that have no other tags, view <$link/> plus all the tags except for the tag [[Foo foo]]
