I was going through the source code of the page and found that, they are using HTML attribute [summary="advanced search engine operators">] in the TABLE tag. You will see a similar snippets in search descriptions, if you search for "Yahoo feature search engine operators" in Google. Not sure if the HTML attribute [ summary="xxxxxx" ] is triggering it.
