Subject RE: question about StandardAnalyzer, differences between solr 1.4 and solr 3.3
Date Fri, 09 Sep 2011 13:40:18 GMT
Hi Marc,

StandardAnalyzer includes StopFilter.  See the Javadocs for Lucene 3.3 here: <>

This is not new behavior - StandardAnalyzer in Lucene 2.9.1 (the version of Lucene bundled
with Solr 1.4) also includes a StopFilter: <>

If you don't want a StopFilter configured, you can specify the individual components directly,
e.g. to get the equivalent of StandardAnalyzer, but without the StopFilter:

<fieldtype name="text" class="solr.TextField">
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.StandardFilterFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
