I understand the differences.  It isn't that I can't find products, but that it takes several extra steps now.  The general site search used to return content when you entered an item name ( or part thereof) , and it doesn't do so with any regularity or pattern anymore.  Just tried again: for http://market.renderosity.com/mod/bcs/index.php?ViewProduct=72240,  I tried a general site search using "Marco"  and there were no hits under store products; for " Hz Marco for M4, " (the full product title), the item does come up on general search, as the 14th on the list ; for "Hz Marco," no hits again.  No problems with the Marketplace search. The Site search used to be pretty useful, and I still usually try it, out of habit as much as anything else.  But it isn't too useful without an exact product name (and not always then).

I've been having quite a few problems with the site search, too.  For a couple of weeks now, nothing at all or nothing relevant is coming up under store products - even copying the item name and pasting in a new search tab.  For example, a search for "SMS Hair" yields the right result in the Marketplace search, but not in the default display on the site search (or the first couple of pages of the 295 keyword results).  Experimenting, "Dead Poses" to searching for "V4 & M4 Dead Poses" brings it up OK in the MP search, but nothing useful in the Site Search (and "V4 & M4 Dead Poses" brings up a different, but equally useless result).    I haven't noticed similar problems with the other result categories (free stuff, articles, etc.).  Searching (+ Advanced search) for "Papoo" brings up no results on Site search (and I was searching from the product page [68111]  itself); "Papoo for M4" brought up lots of results, but not that item.  I'm baffled by whatever organizing principle there is for what DOES come up. Up to a couple of weeks ago, I had no problems with this feature but currently Google is far more useful.  Could browser security have something to do with this?  I can't cut & paste directly in the forums anymore either (and get a message to that effect) and Firefox did an update 2 or 3 weeks ago.  Except for popup blockers & redirect filters, I can't see anything that would affect things here (disabling them has no effect).
