I searched the archives a bit to no avail, so apologies if this has been covered before.

I sort of love browsing the dictionary pointlessly, running into fun or interesting words.  The absolute best feature on jisho.org is the wildcard search - I love sticking a kanji between two * and seeing everything EDICT has it in.  HOWEVER, as we all know, EDICT is far from comprehensive.  I am familiar and comfortable with the J-J dictionaries on yahoo, goo and alc, but (as far as I can tell...) they do not allow wildcard searches. 

Am I just missing this feature on one of those dictionaries? It's very possible, because I have not read their documentation. Or is there possibly a J-J dictionary that allows this?  I would be fine with J-E too, but to my knowledge the vast majority of the ones on the web are just frontends for EDICT so there probably wouldn't be much point there.
