Forum Search Mac-unfriendly

Just noticed that you cannot search this forum for anything "Mac".

Tried to search for
labeler software mac
and got:
The following words are either very common, too long, or too short and were not included in your search : mac
(The only reason was "mac" being too short.)
Given the background of this site, this came as a surprise to me.

The search does, however, accept four-letter words.

I've seen forum softwares reject two-letter words for search before, but not three-letter words.

Is there any way to change that?

P.S.: Didn't know where to put this post (the other two categories I considered seemed to be administrators-only), so I put it here.
