Hi Nick - it wasn't so much a limit of the forum software itself, but rather of the MySQL database itself...

But that limit is something that I can adjust in the database server. I have done that so now you should be able to search for 3 letter words such as "dxf" using the built-in forum search now.

The google search method would also work, but I don't think that Google has indexed every single bit of the entire forum, while the built-in one will definitely search through every single post.
