neo4j

I have indexed some documents (nodes of neo4j) with a boolean property which not always is present. Eg. Node1

label : "label A"

Node2:

label : "label A" (note, same label of node1) special : true

The goal is to get Node2 higher than node 1 for query "label A".

Here the code:

Index<Node> fulltextLucene = graphDb.index().forNodes( "my-index" );
Sort sort = new Sort(new SortField[] {SortField.FIELD_SCORE,
                     new SortField("special", SortField.????, true) }); 
IndexHits<Node> results = fulltextLucene.query( "label", new QueryContext( "label A").sort(sort));

How can I accomplish that?

Thanks
