Hi! I don't think the easy solution will work for me, because I'll have more than two fields in a group - perhaps 6 - 10.
However using span queries looks very promising. I'll investigate that. I see setPositionIncrement() only on the Token object. Is there a way to set this when adding a field to the document, so that the first token get its position pushed away. I would prefer not to modify my analyzer if possible.
