---------------------------------------
Attachment: LUCENE-4242.patch
I cleaned up the patch a bit ... only issue now is it causes failures in
TestRandomFaceting.
> UnInverted cache uses term freq to filter out terms (but deleted docs are
> included in the freq count)

> Key: LUCENE-4242
> URL: https://issues.apache.org/jira/browse/LUCENE-4242
> Project: Lucene - Java
> Issue Type: Bug
> Components: core/index
> Affects Versions: 4.0
> Reporter: roman
> Priority: Minor
> Attachments: LUCENE-4242.patch, LUCENE-4242.patch, LUCENE-4242.patch

> TermEnum.docFreq() count is used to compute uninverted index
> (DocTermOrds.uninvert()). The code goes like:
> final int df = te.docFreq();
> if (df <= maxTermDocFreq) {
> So, if there are deleted documents in the index and maxTermDocFreq is
> low, then the term will be excluded (even if the freq of the livedocs
> is OK). Most likely, the cache will be incomplete.
