Search doesnt bring up all of the results?

[RRsDJ]

Im looking in the classifeds for a 16610. Ive searched Submariner and 16610 and not all of the listings are showing up. Im having to do a google search for submariner or 16610 to view all of the current ads.

I'll use the member faingator as an example. Hes selling a 16610 HERE but his ad doesnt show up in the search results:

faingators' newest post date in his ad is Oct. 10, 2012 so it should show up in the search link above but theres only 8 listings showing up for Submariner in the month of Oct., which I know isnt accurate, theres been plenty of Subs that have been sold / traded or are current for sale / trade. Theres a lot more members ads that arent showing up as well in the forum search results, im just using faingator as one example. Its not that big of a deal since I can find them through google but I wanted to draw attention to it if its an easy fix for the webmaster.
