[Neo] Request a sample code to illustrate finding all nodes where key < value

I'm almost positive I gave such an example in another thread
recently... anyways:

IndexService index = new LuceneFulltextQueryIndexService( neo );
index.index( myNode1, "someKey", 150 );
index.index( myNode2, "someKey", 100 );
index.index( myNode3, "someKey", 170 );
index.index( myNode4, "someKey", 230 );

// This will return myNode1, myNode2 and myNode3
index.getNodes( "someKey", "[0 TO 170]" );

See http://lucene.apache.org/java/2_9_1/queryparsersyntax.html#Range%20Searches
for more information.
