It seems to me that an increasing number of people have been trying to search the forums, only to be frustrated by eventually posting a question and getting the reply, "That's been asked before - search the forums!"
Well, because of a quirk in these forums that I have seldom seen elsewhere, that's just not as easy as it sounds.If you are in the Sandbox, for instance, and you type in search words and hit enter,
your results only pertain to the Sandbox; of course, the same is true for any other section.
If you want to do a global search (and really, who doesn't?

), start by clicking on Home (the one in the line
HOME>HELP>SEARCH..., not the one in the
Home>Support>Forum>Help... line at the very top of the page) and launch your search from there. You'll probably end up with so many results you need to trim your search!
I know this is a simple and obvious tip, but it's also obvious to me that a great many people struggle with that when they first arrive here. Hope someone finds it helpful.
