It will be nice to have access to payloads when doing SpanQuerys.
See http://www.gossamer-threads.com/lists/lucene/java-dev/52270 and http://www.gossamer-threads.com/lists/lucene/java-dev/51134
Current API, added to Spans.java is below. I will try to post a patch as soon as I can figure out how to make it work for unordered spans (I believe I have all the other cases working).
/**
* Returns the payload data for the current span.
* This is invalid until {@link #next()} is called for
* the first time.
* This method must not be called more than once after each call
* of {@link #next()}. However, payloads are loaded lazily,
* so if the payload data for the current position is not needed,
* this method may not be called at all for performance reasons.<br>

* WARNING: The status of the <b>Payloads</b> feature is experimental.

// TODO: Remove warning after API has been finalized
