You can create indexes with different names, yes. You cannot change the index name afterwards. > > I am wondering how to use the indexName,and how it works .

I have not find something useful. thanks :) > Query times increase with bigger indexes (and with different keys) so try to keep indexes as small as possible, but if you're looking to do compound queries then you'll have to index key/value pairs from different keys into one index. Each index node index / relationships index becomes its own lucene index (the backend used to provide the default index implementation in neo4j). There's a pretty good outline of indexing at http://docs.neo4j.org/chunked/snapshot/indexing.html > _______________________________________________ > Neo4j mailing list > [email protected] > https://lists.neo4j.org/mailman/listinfo/user > -- Mattias Persson, [[email protected]] Hacker, Neo Technology www.neotechnology.com _______________________________________________ Neo4j mailing list [email protected] https://lists.neo4j.org/mailman/listinfo/user
