Let's not confuse the functionality of an indexer/search engine with the functionality of a search interface. An indexer is used to find. The finding process can be enhanced with features that are not a part of the indexer. Spell checking is one of those features. The exploitation of a thesaurus is another. Thus, creeping featuritis. By exporting the words from an index and feeding them to a dictionary you can capture queries to the user interface, enhance the interface, reformulate the query, and then send it on to the search engine. Spelling correction is not a feature of the indexer/search engine, but it is a feature of the user interface. Similarly, exploiting a thesaurus (an authority list, a controlled vocabulary, or whatever you want to call it) works in the same way. Use it to reformulate and/or suggest alternative queries to be applied to the index. Thesauri are not an integral part of the indexer, per se, but the interface as a whole. Faceted browsing is just fancy way of using controlled vocabularies to access the content in the index. Boolean operators, fielded searching, phrase searching, and relevance ranking are a part of indexers/search engines, but just because they work against the indexer does not mean you use their particular syntax in the user interface. Yet again, you create the interface and translate that into the language of the indexer/search engine. (That is *really* what Z39.50 and SRW/U are for.) Not the other way around. -- Eric Morgan I'm hiring a Senior Programmer Analyst. See http:// dewey.library.nd.edu/morgan/programmer/.
