Yeah the search function is really screwed up why the admin insists on using an obscure forum software rather than something like vBulletin is beyond me. If you want to search just type in site:originaltrilogy.com/forum "search term" on google.
Nope. All you need in google is: originaltrilogy.com "search term".
Also, I made a bookmark/favorite in my browsers so I don't have to type that every time I search.
