Adobe Reader search function is unacceptably slow--alternatives?

I'm happy with the rendering performance of Adobe Reader, but not with the search speed. It's basically useless for searching any document longer than 100 pages because it takes so long. Are there any programs out there with a much better search function? It needs to have comparable or better PDF rendering. I've tried PDF Reader Pro but the rendering performance was crap. iBooks rendering speed is also crap.
