Look at the org.apache.lucene.codecs.Codec class, it has a method: public abstract StoredFieldsFormat storedFieldsFormat(); which returns a stored fields format used to encode your stored fields written by the index writer. > > Where can I apply the field compression and provide parameters for the > compression level? Look at Lucene41Codec this is where the field format is created. you can use your own codec (subclass codec) and plug it into the IndexWriterConfig to apply your own settings. > > The documentation about the 4.0 and 4.1 releases with examples about > the changes aren't well documented.

I don't think we have examples on the wiki for that stuff but we should I guess. simon > > Regards, > > Bernd > > --------------------------------------------------------------------- > To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org > For additional commands, e-mail: java-user-h...@lucene.apache.org > --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
