: Well some client inquiries if it's possible to expand such simple words : and does Lucene have an API for this logic? Because all I read was the : stemming logic for Lucene was the other way around which is, example : "flashing" it will be trimmed to the root word "flash" when searched.
there are two fundemental approaches (that i know of) to stemming: reduction and expansion. reduction can either be algorithmic, or morphologically/dictionary based. expansion esentially has to be morphologically based. The SnowballAnalyzer uses the Snowball stemming algorithm, which is a reduction approach to stemming. if you want an expansion based appraoch, you have to have a dictionary. Lucene doens't provide one of these, but that doens't mean you can't use one if you find one -- it's been a while since i looked but the only ones i've ever seen were only commercially avialable. http://en.wikipedia.org/wiki/Stemming -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
