Hi member of digitalsmiths, I also implemented SpanNearQueryNode and some QueryNodeProcessors. Most possible you can solve your problem by using QueryNode#setTag: In QueryNodeProcessor#preProcessNode you can set and remove and reset a Tag to mark the AndNodes that should became SpanNodes; after this you can use the QueryNodeProcessor#postProcessNode method to substitute this AndNodes in your OrNodes.
