Title: If there is no sutable result for user search, user is redirected to activitypage

In the script, there is a rule, which says, that if no result matches the search query, user is redirected to activitypage.php?search=. If no result is found, user should be noticed about that fact, or redirected to classic phpBB's search with "author" input prefilled and submitted.
