Yahoo! just announced a new beta tool named Y!Q BETA, which enables "search by example" function, basically contextual search. Chris Sherman has an extensive write up on this. Many of you, about 30%, use firefox, so try out the firefox plugin for it. Jeremy Z. has a big write up on this at the Y! Search Blog.
For forum coverage, I recommend checking out the Search Engine Watch thread, where Chris Sherman, Nacho Hernandez, Detlev Johnson, Daniel Brandt and Danny Sullivan all comment.
