I'm not sure of your definition of "proper search", but bing seems to have a reasonably flexible search syntax (http://msdn.microsoft.com/en-us/library/ff795667.aspx).

I'm personally going to give it and DDG a try over the next couple weeks, just in case either is currently significantly better for tech related searches.

So far Duck Duck Go is looking like a potential win.
