Actually this message - 'Sorry, no matches found- will appear at the following situation:

You open your browser and click on new posts. Later you open a new browser and use the new posts function again (so it will make an updated search). You end up closing the window with the new search, and try to browse thriough the window with the old search, so if you use the "old" window to try to browse through the pages of threads 1, 2, 3, etc, you'll get the message "Sorry, no matches found", because that "New Posts" window browser is outdated. You'll either have to click at "New posts" again, or open it in another window. It always happen to me if I do these things I mentioned, because I have the habit of opening several separate windows for every single thread I'm going to read.
