Re: [Neo4j] Default Analyzer in Index Framework

 Hi, Mattias.

 That's exactly what we did. One interesting note: the query and get methods
 seemed to work without lower casing the search term (maybe the analyzer is
 used to parse the query?), but for native lucene queries we needed to
 lowercase them.  All good now!  Thanks for the tips.

 You're right there, the analyzer is used both for altering added values as
well as parsing queries.

  Hi Rick,
 
  yes you can do that, but not in a super easy way. What you'd have to do
  right now to get it working is to make sure you create an index with a
  special analyzer which converts everything to lower case (both additions
 and
  queries), effectively making it case insensitive. So create a class like
  this:
 
 public class LowerCaseAnalyzer extends Analyzer
 {
 @Override
 public TokenStream tokenStream( String fieldName, Reader reader )
 {
 return new LowerCaseFilter( Version.LUCENE_31, new
  KeywordTokenizer( reader ) );
 }
 }
 
  and make sure you create your index with a configuration map like:
 
 IndexNode index = graphDb.index().forNodes(
 myCaseInsensitiveIndex, MapUtil.stringMap( analyzer,
  LowerCaseAnalyzer.class.getName() ) );
 
  then this will work:
 
 index.add( node, name, Rick Bullotta );
 index.query( name:\rick bullotta\ ); // == returns that node.

  Anyone able to provide some insights on this?
 
  Thanks.

  When not using fulltext indexing, what Lucene Analyzer class does Neo4J
  use?  It seems that non-fulltext index searches are case sensitive -
 we'd
  like to change that behavior.
 
  Thanks for any help/guidance/examples!
