If you select the "search" option you'll find a "keyword" box and can search/find on any text or number string. Also, if you "select" all threads and "collect" them, you'll have one sequential list of posts. Just use your browser's "find" [Ctrl + F] function and enter the text string. Remember to first click inside the frame where the "collected" text is displayed. Since Bb is a frameset, if you hit Ctrl + F in the menu or header you won't find what you're looking for, but you will if you select the frame you're trying to search.
