wordnik is indexed at OneLook, but doesn't seem to have been re-scanned for almost two(2) years - maybe that's why omegapsic(al) (order) doesn't appear there.

this is actually a problem at OneLook, since the founder is supposedly no longer actively involved; they no longer do automatic/periodic updates of all their content, and (at least us lesser) lexic drudges have to *poke* the OneLook drudge(s) to do an update.
