Hi Marc, StandardAnalyzer includes StopFilter. See the Javadocs for Lucene 3.3 here: <http://lucene.apache.org/java/3_3_0/api/all/org/apache/lucene/analysis/standard/StandardAnalyzer.html>
This is not new behavior - StandardAnalyzer in Lucene 2.9.1 (the version of Lucene bundled with Solr 1.4) also includes a StopFilter: <http://lucene.apache.org/java/2_9_1/api/all/org/apache/lucene/analysis/standard/StandardAnalyzer.html> 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"> <analyzer> <tokenizer class="solr.StandardTokenizerFactory"/> <filter class="solr.StandardFilterFactory"/> <filter class="solr.LowerCaseFilterFactory"/> </analyzer> </fieldtype> Steve > -----Original Message----- > From: Marc Des Garets [mailto:marc.desgar...@192.com] > Sent: Friday, September 09, 2011 6:21 AM > To: solr-user@lucene.apache.org > Subject: question about StandardAnalyzer, differences between solr 1.4 > and solr 3.3 > > Hi, > > I have a simple field defined like this: > <fieldtype name="text" class="solr.TextField"> > <analyzer > class="org.apache.lucene.analysis.standard.StandardAnalyzer"/> > </fieldtype> > > Which I use here: > <field name="middlename" type="text" indexed="true" stored="true" > required="false" /> > > In solr 1.4, I could do: > ?q=(middlename:a*) > > And I was getting all documents where middlename = A or where middlename > starts by the letter A. > > In solr 3.3, I get only results where middlename starts by the letter A > but not where middlename is equal to A. > > The thing is this happens only with the letter A, with other letters, it > is fine, I get the ones starting by the letter and the ones equal to the > letter.
