[jira] [Created] (LUCENE-4859) Expose more stats on IndexReader

JIRA jira@apache.org
Shai Erera created LUCENE-4859:
----------------------------------

             Summary: Expose more stats on IndexReader
                 Key: LUCENE-4859
                 URL: https://issues.apache.org/jira/browse/LUCENE-4859
             Project: Lucene - Core
          Issue Type: Improvement
          Components: core/index
            Reporter: Shai Erera
            Assignee: Shai Erera


IndexReader exposes stats like totalTermFreq(term) and docFreq(term). I'd like to add more stats from Terms, e.g. getDocCount/getSumDocFreq/getSumTotalTermFreq(field) for convenience. The implementation is very easy to do on CompositeReader, so I'll add these impls to BaseCompositeReader. I'll attach a patch shortly.
