I've had this problem numerous times. Upon entering a search term string in the search box, the error comes back that I haven't entered enough words because it's under the minimum, even though I add words after. Anyone have similar experience?
It isn't called "IsBot", it is called "Is Bot: something else here" and it is impossible to search for. Try the term "registra*" in "all mods" "titles only" and it should come up.
