Sorting by relevance is possible via http://components.neo4j.org/neo4j-index/apidocs/org/neo4j/index/lucene/LuceneIndexService.html#getNodes(java.lang.String,%20java.lang.Object,%20org.apache.lucene.search.Sort). Exposing this sorting thingie would require you to add that in the rest code as well (as you probably could guess). But the IndexService doesn't support querying for more than one property at a time.
However, there's a new indexing framework in the making over at https://svn.neo4j.org/laboratory/components/lucene-index/ which allows you to do these types of queries. This new framework will probably make its way into trunk rather soon and eventually replace the indexing found in neo4j-index component today. So the answer is no if you use neo4j-index component (which REST does). But it's yes if REST were to use the new framework instead. I'll commit the additions regarding sorting and all that soon (I'm laborating with it a.t.m.). You could f.ex. ask a query like: for ( Node node : myTitleIndex.query( new QueryContext( "+title:foo* description:bar" ).sort( Sort.RELEVANCE ) ) {} 2010/7/16 Andrew Mutz <andrew.m...@appfolio.com> > Hi all, > > I've been evaluating using Neo4J for a project at my company and have been > consistently impressed with it's capabilities.
