Scratch that... you can do:
myNodeIndex.query( new QueryContext( "name:*...@gmail.com" ).sort( new Sort(
new SortField( "name", SortFie
ge", 0, 100, true, true ) ).sort( new Sort( new SortField( "age",
SortField.INT ) ) ) );
So that you must know what you're doing... would that be ok or any other
better idea?

If this is a one-time batch insertion then should really use the batch

these things. It's much faster for imports of this sort and you don't have
