Over on MSN Search Weblog there are explanations of the new search operators.
I like the InBody and Contains operators.
The example they give for finding pages that link to a target page using specific anchor text is totally off though.
inbody:miserable inbody:failure link:www.whitehouse.gov/president/gwbbio.html
Although this will match text found in the anchor text of links – this matches all body text. So this query actually searches for pages with body text including the words “miserable failure” and links to the president’s bio page. This doesn’t limit the results to only pages with “miserable failure” as outgoing anchor text, so the example is incorrect. Pages with “miserable failure” in the body text can still link to the president’s bio using different anchor text and still be returned in this query.
