As we know, our forum lacks an advanced search function. For this we apologize. But fortunately there's a strong workaround that's easy. You can use a Google search that yields excellent results. Here's how:
site:forum.baldursgate.com, ___ (term)
For example, to search the BG:EE forums for just the word: katana
And what is pretty cool here is that if you click on the ">>" to the right of each result, it tabs out and highlights exactly where it is on the forum page. Click that and it takes you right to the page of the thread it's on.
For easy access you can bookmark any such search in your browser and then just open it and tailor it as shown above to customize the search terms.
