[Neo4j] Index search with more than one key

[Mattias Persson]

There's a prototype implementation of a new index which solves this (and
some other issues as well, f.ex. indexing for relationships). The code is at
https://svn.neo4j.org/laboratory/components/lucene-index/ and it's built and
deployed over at http://m2.neo4j.org/org/neo4j/neo4j-lucene-index/

The new index isn't compatible with the old one so you'll have to index your
data with the new index framework to be able to use it.

    IndexProvider provider = new LuceneIndexProvider( graphDb );
    Index<Node> myIndex = provider.nodeIndex( "users" );

    myIndex.add( myNode, "type", "value1" );
    myIndex.add( myNode, "key1", "value2" );

    // Ask lucene queries directly here
    for ( Node searchHit : myIndex.query( "type:value1 AND key1:value2" ) )
    {
        System.out.println( "Found " + searchHit );
    }
