While I was inundated with conferences a couple of weeks ago, I missed s a nice article by Stephanie Lemieux at User Interface Engineering (a site I recommend in general) entitled “Designing for Faceted Search“. It briefly explains faceted search and offers some usability tips. It’s not quite as comprehensive as my upcoming book, but it’s also free and is somewhat less than 100 pages.
Of course, I’m delighted that she uses a couple of Endeca-powered examples (NCSU Libraries, Buzzilions). She also cites the Financial Times, but links to the ft.com (which I believe is powered by FAST, a subsidiary of Microsoft) rather than the recently launched Newssift, which uses Endeca.
Just one quibble: she says that “Just 3 facets with 5 terms each can represent 243 possible combinations.” I suspect she transposed the 3 and the 5. The right number of combinations is 125 = 5^3, since a combination represents 3 independent selections from 5 possible choices.
