Despite the assurances from the Google employee (Danny Sullivan) at the end of the article, I have not found quoting a phrase to work reliably, especially if trying to exclude the phrase. But what I have found to work is typing the quoted phrase in twice in the same search query. Weird, but so far, effective. And no, I don't remember what the searches were for. Wish I did. Not for a second am I accusing Danny Sullivan of dishonesty. I take him at his word. Quirks abound on the net.
