If it's the forums search we haven't changed it since launch. The forum search does have creation date... so I'm a bit confused.
I'm positive they used to be there! Their absence makes it much more difficult to see if someone else has already posted on a particular topic. And while we're at it, Boolean capabilities would be greatly appreciated, too (just about every search engine in the world beside ours has that feature...)
Thanks -- grumbling Dave K.
