There are three different ways to search, and they all do slightly different things.
1. If you are in a thread, and you type something in the box above, and click the search button, it will just search in that thread. (note: if you are on the forum index page and do that, it will search all the threads)
2. If you click 'search' on the navigation bar above (between 'Home' and 'My Bookmarks'), it takes you to a basic search page that searches all the threads. This is the same thing that happens if you use method #1 from the forum index page.
3. If you click the magnifying glass next to the box above, it takes you to an advanced search page where you can get much more specific about what and where you are searching, and provides options on how you want to see the results.
Do #3 with "Minnesota Wild" and tell me what you find.
