Possibly these are classed as "common words", and therefore not included in the search index. I'm not sure that's a correct classification, though...
It only happens in the game. "everytime" returns 0 results
EDIT: I also tried "everyone", "everything", and "everybody"
All of them gave 0 results.
EDIT2: This also happens with MANY other words, like CRMC, LCRY,
This will be even more annoying when version 90 is released...
