Values are not interned, but in a single field cache entry (String[]) the same String object is used for all docs with that same value. But... I think StringIndex is more commonly used in both Lucene and Solr than String[] (sorting, faceting, etc) so double check that it's not StringIndex you should be looking at. -Yonik Apache Lucene Eurocon 2010 18-21 May 2010 | Prague --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
