Subject Re: how to filter numeric values?
Date Mon, 22 Mar 2010 19:14:48 GMT
Why not just use SimpleAnalyzer? From the javadocs:
An Analyzer<http://lucene.apache.org/java/3_0_1/api/all/org/apache/lucene/analysis/Analyzer.html>
that
filters LetterTokenizer<http://lucene.apache.org/java/3_0_1/api/all/org/apache/lucene/analysis/LetterTokenizer.html>
 with LowerCaseFilter<http://lucene.apache.org/java/3_0_1/api/all/org/apache/lucene/analysis/LowerCaseFilter.html>

<http://lucene.apache.org/java/3_0_1/api/all/org/apache/lucene/analysis/LowerCaseFilter.html>
