Advanced filtering #156

Oh I see you are pasting in an all-lowercase query, this doesn't work (but I'm not sure if that's a use case worth mentioning). The part which works is typing in lowercase and having it autocomplete to the correct casing.

What would be your use case to paste in a lowercase query?
