That dosen't mean you can't search three letter words like 'cam', 'HMF', 'FMF' etc...

All you have to do is add an asterisk (*) to the beginning or the end of the three letter word.

cam* or *cam
*HMF or HMF*
etc...


Adding the asterisk to either end may result in different results meaning *cam may have different results that cam*. Try them both for which ever three letter word you're trying to search to get the most results.
I've seen this advice given as a workaround, but the fact is that an asterisk (*) means the same as "1 or more of any character", not "0 or more". So for instance, using HRC* as a search term will not turn up this post, but will turn up posts containing "HRC," "HRC." "HRC/FMF" etc. This is quite misleading and severely limits search results for 3-letter terms for which there's no other way to search.
