Thanks Mattias. One node is a Foo node and one is a Bar node. Maybe I am being too fancy; I could just use 'NAME' for any type of node. I'm a little confused about the query string below. Should it perhaps be "NodeType:Bar" AND "Name:Bar 1" ? I'm not getting why the property name is inside the quotes for one predicate and not the other (below.)

I'm assuming you have NodeType/Name for both ok? So... a query like this would look like: nodeIndex.query( "NodeType:Bar" AND Name:\"Bar 1\"" ); 2011/11/1 Bill Baker <bill...@billbak.com> > Hello, > > I have an index and add my nodes to it as I create them.
