I think everyone is well aware the Simple Machines search algorithms fail miserably for some reason, and thus even simple film title searches on these forums produce few decent results.
But don't forget you can always use Google:
For instance:
You put whatever your search criteria is. In this case "Jesse James" and follow it up with "site: filmspotting.net/boards"
(by the way, it's pretty simple bit of HTML to change the search functionality on this site to use Google!)
