does this site have a real search feature that can help?

I have been trying to get Rf2 to run in dx-11 for months. Using the search feature of this site is an exorcise in futility. Here is a sample of the awesome feature in action

.....


can anybody tell me, either; A, how does anything on this search results list help me? or B, is there a way to spell "run" or "in" or "dx11" with more letters, fewer letters, or a way to spell any of those words in a less common way apparently or C, how to run rf2 in dx11 after using the pulldown, selecting dx11 beta, downloading it, starting it and watching it crash? Yes, I have turned off all add ons. or D, should i just keep using dx9 and loving rf2? thanks for any real help for a frustrated user.

 

That's how it works in Xenforo, there was another long discussion about this already.
We might eventually look into something to improve this, until then Google site search is your friend
