Examples of org.neo4j.index.lucene.ValueContext

org.neo4j.index.lucene.ValueContext
ValueContext allows you to give not just a value, but to give the value some context to live in.

    node2.setProperty("label", "Secondos, and Nodos");
    node3.setProperty("label", "Tertios, Nodos");
    node4.setProperty("label", "Quartios- Nodos");


    index.add(node1 ,"score", new ValueContext( 1 ).indexNumeric());
    index.add(node2 ,"score", new ValueContext( 0 ).indexNumeric());
    index.add(node3 ,"score", new ValueContext( 2 ).indexNumeric());
    index.add(node4 ,"score", new ValueContext( 3 ).indexNumeric());
