I'd amend that to the sorry state of any word-dependent search. Pity some poor soul (me on some occasions) who must look for a term about which he knows little, but that's also the name of: 1. a rock band or 2. some new bit of technology. You'll be flooded with a great pile of hay out in which you must look for that needle. You don't even know enough to come up with limiting terms. That said, Google search usually does a good job. My gripe lies with the utter sloppiness of Google Books, scans made by poorly paid people who didn't care and entered into a database whose contents shows no awareness of the need for additional information about that book.
