Looking at the Wiki ( http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters ), it looks like the solr.StandardTokenizerFactory changed with Solr 3.1 .
We use solr.KeyWordTokenizerFactory for our middle names (and then also throw in solr.LowerCaseFilterFactory to normalize to lower case). It treats the entire field as a single token, and in general doesn't "futz" with what came in. You might try the analyzer panel on the admin web page to see what exactly is happening during indexing and analysis. JRJ -----Original Message----- From: Marc Des Garets [mailto:marc.desgar...@192.com] Sent: Friday, September 09, 2011 5:21 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. My guess is that it considers A as the English article but I do not specify any filter with stopwords so how come the behaviour with the letter A is different from the other letters? Is there a bug? How can I change my field to work with the letter A, the same way it does with other letters.
