Search results accuracy issue?

Just wondering if anyone else has posted any issues with the accuracy (or lack thereof) of the search bar here as of late. It does not seem to be respecting quotation searches (" ") or the AND wildcard.

For example, I search for "Dave Matthews" and technically I should only get results for posts that have "Dave Matthews" in them. However, it seems to be returning results of anything with dave OR matthews in them, which pretty much renders searching useless unless it's a unique word.

Try pressing the 'magnifying glass' (search) button without any terms. This usually brings up the Advanced Search on most vBulletin sites.
