Doug Cutting commented on LUCENE-1001:
--------------------------------------
> Would it be simpler to just use a SortedSet?
TreeMap is slower than a PriorityQueue for this. With PriorityQueue,
insertions and deletions do not allocate new objects. And, if some items are
much more frequent than others, using adjustTop() instead of inserting and
deleting makes merges run much faster, since most updates are then considerably
faster than log(n).

> Reporter: Grant Ingersoll

> It will be nice to have access to payloads when doing SpanQuerys.

> Current API, added to Spans.java is below. I will try to post a patch as
