[Koha] error message for keyword searches

Hi all, My library has recently finished cataloging our *entire* collection into Koha, which was a great and easy process! However, now comes the troubleshooting part, and we're running into a LOT of problems. Unless I'm searching for a specific title or author, I get this as the result: Error: Can't call method "as_usmarc" on an undefined value at /usr/share/koha/lib/C4/Search.pm line 2384. That error message is yielded for nearly every keyword search, for things that I know are in our collection. Suggestions? I am using the latest Koha installation.
