Microsoft at work on advanced search
News.com has an overview of work on Implicit Query and other advanced search and UI techniques at Microsoft Research. This work is lead by Sue Dumais, ex- of Bellcore's Latent Semantic Indexing group, and really smart (and nice) person. Don't go looking for all this stuff in the next Windows release, necessarily. Microsoft has a long history of banging away in the search engine space without getting much out the door. Best wishes to Sue, but the road from research to product in this area seems to be a long and winding one.
