: The SnowBallAnalyzer seems to offer stemming. The StandardAnalyzer on : the other hand has a bunch of other niceness. What is the best practice : of leveraging both these analyzers while indexing and searching? Do I : chain these up somehow and if so what apis do i look at for doing so? Do : i implement my own analyzer and use both these two process the tokens?
the Analyzer class is already designed to making chaining very easy -- but not Analyzer chaining, TokenFilter chaining. if you take a look at the source for StandardAnalyzer and SnowBallAnalyzer it should (hopefully) be very obvious how to write your own (10 line or less) Analyzer that gives youall the goodness you want from both... http://svn.apache.org/viewcvs.cgi/lucene/java/trunk/src/java/org/apache/lucene/analysis/standard/StandardAnalyzer.java?rev=219090&view=markup http://svn.apache.org/viewcvs.cgi/lucene/java/trunk/contrib/snowball/src/java/org/apache/lucene/analysis/snowball/SnowballAnalyzer.java?rev=151459&view=markup ...if you literaly just want to add snowball stemming to the end of StandardAnalyzer, then i *think* something like this would work... Analyzer a = new StandardAnalyzer(stoplist) { public TokenStream tokenStream(String fieldName, Reader reader) { return new SnowballFilter(super.tokenStream(fieldName,reader), "yourChoiceOfStemmerName"); } } -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
