public class SummaryStatsCollector2
extends SummaryStatsCollector

This HitCollector is called for every version we want statistics for. It will load the related issue document and upgrade the stats counter. Going through the Lucene index this way is faster for a large number of versions than firing individual counting queries, mainly due to JIRA's excessive permission checking. The downside is that each issue document has to be fetched, which by itself is slower than just working on the hit index. Yet, it's still about 50% faster than using individual queries. The HitCollector can be configured to discriminate by different fields using the keyField.
