I just tried searching the forum for a thread I started a few months ago - by searching for the word "spam" (which was the subject of the thread). I got no hits newer than Apr 2007. Finding that a bit odd, I tried a few other search terms and found the same results - nothing newer than Apr 2007, except in cases where the post was made after the forums were updated. So, it appears that search won't return any hits from about 4/25/07 to about March 2017.
