I haven't really been able to search for anything, because the search seems too restrictive. Everything I want to search is either too short, too common, etc.
I searched for "zumo 665" and it discarded 665 because it was too common.
I can't search for zumo because it's too short (I guess).
I understand that some 3-letter words are too short, and I've run into this problem on other forums, but I've searched for a handful of other 4-letter words, and had no luck at all.
I'm not sure what the shortest allowable word is, but I don't think anything I've tried to search for in the past few weeks has been considered an 'acceptable' search.
