I have to agree with this; I like the site, but a quick search for a few books that sprung to mind turned up either a pile of irrelevant results (as someone said above, sort out your stopwords; if I search for "The Gunslinger", "The Girl who Kicked the Hornets Nest" is not relevant) or nothing at all once I started trying distinctive title (Cryptonomicon, Accelerando). I'm keen for someone to do a better job on book recommendations for me, but I think this needs a lot of improvement before it'll do the trick.
