    For RemoteGraphDatabase there is an implementation of the IndexService called RemoteIndexService.
    In order to use it you need to first create and expose the IndexService on the server:

    EmbeddedGraphDatabase graphDb = ...
IndexService index = new LuceneIndexService(graphDb);
BasicGraphDatabaseServer server = new LocalGraphDatabase(graphDb);
server.registerIndexService(index, "lucene index");
// Expose the server through RMI as usual...

    Then on the client side you would do:

    RemoteGraphDatabase graphDb = ...
IndexService index = new RemoteIndexService(graphDb, "lucene index");
// business as usual...

    The next update of RemoteGraphDatabase will use the new index API of Neo4j introduced in 1.2, that will make this much more convenient.
