I find the "Search" box at the top of the page utterly unhelpful. I don't know why it is like that.
It searches for the words entered, starting in the most recent posts, and displays each post containing those words, no matter whether they form the subject of the post or not.
Usually, it does not find any post on that topic at all.
Even entering the title of a forum thread does not locate that thread.
The only good feature is that the search results page includes a suggestion to try Google search. This yields a search restricted to the ATA forums, and it works perfectly.
I now enter a random word in the "Search" box, so I can access the Google search as a second step.
I wonder whether this problem can be fixed?
