can't get results searching for my post

Made a post a few weeks ago and didn't get any replies so thought I'd try "searching" for it myself.  Tried several ways but did not get any results to my post.  I can only find it searching by username or looking under "my forums" or browsing the actual sub section of the forum myself but nothing on searching.  Am I doing something wrong?  My post's title starts with "alternator stops charging" and is posted under "trucks and suv's" "pathfinder".  I searched "alternator", "alternator stops charging" with no results. Tried, title only, title and body etc.  Any suggestions as to what I may be doing wrong?
