----------------------------

Kudos Aaron, this is cool for what I need. 

I just integrated in my project, upgraded to 3.0 just to get this in. But I am having an issue in my first test:

java.lang.ArrayIndexOutOfBoundsException: 1
	at org.apache.lucene.util.PriorityQueue.initialize(PriorityQueue.java:96)
	at org.apache.lucene.search.HitQueue.<init>(HitQueue.java:67)
	at org.apache.lucene.search.PagingCollector.<init>(PagingCollector.java:43)
	at org.apache.lucene.search.PagingCollector.<init>(PagingCollector.java:39)
	at org.apache.lucene.search.IterablePaging$PagingIterator.search(IterablePaging.java:158)
	at org.apache.lucene.search.IterablePaging$PagingIterator.<init>(IterablePaging.java:151)
	at org.apache.lucene.search.IterablePaging.iterator(IterablePaging.java:140)
	at ...CombinedLuceneDBStep.proceed(CombinedLuceneDBStep.java:71)

I use it like this:
            MultiSearcher ms = new MultiSearcher(indexes);
            TotalHitsRef totalHitsRef = new TotalHitsRef();
            ProgressRef progressRef = new ProgressRef();
            IterablePaging paging = new IterablePaging(ms, lucquery, NB_LUCENE_HITS_PER_BATCH);

I have no clue where the issue lies, I am using MultiSearcher , and norms are disabled. Or maybe I screwed up something while upgrading to 3.0... I got the files as of feb 11th.
