Leveraging Faceted Browsing to Improve Search
I always think that the term "search" is a bit of a misnomer in the information retrieval field, for, as the "retrieval" hints, users are generally only interested in "find". To this end, I was really impressed by a demonstration (but unfortunately not by the price!) of endeca's search tool today (you would have thought that I'd remember the exact name, but you can find it for yourselves). Among other things that I liked was the combined keyword search box with metadata facets displayed beneath, and the fact that you could search within your results as you filtered down among the facets. Filters could be removed and deleted at will to modify your search, which was excellent feedback, and worked very neatly. Very neat.

And on that sort of a note, here's an article on Metadata based search and browse (for the NSW Office of Fair Trading intranet) via Column Two.
