@Leda2 - Where you start your search in ATP, it will limit the results that are displayed depending where you are. For instance if you are in the forums area then it will only show forum results:
If you are in the plant database then it will show only database results:
But if you start your search from the home page it searches just about everything on the site. I see that a search for Hoya returns about 45 pages of results.
Took me awhile to get that concept - but I like it. It lets me focus my searches if needed.
Ohh - and
