LookAhead Searching

It's not quite a taxonomy but it does work from a controlled vocabulary. Surfwax, known for a variety of Web-search toolsets, is making its look-ahead technology available to webmasters for a fee. Searcher can select from a list of words or begin to type and be presented with suggestions. You can see the vocabulary listings and how it works at the Surfwax News Accumulator. Gary Price describes the service in Surfwax Offers Look-Ahead Technology for Web Sites at SearchDay (Sept 19).
