Mailing List Archive: Question for SoftDeletesRetentionMergePolicy#numDeletesToMerge

Hello,

Since the liveDocs of a CodecReader already excludes soft-deleted
documents, the condition "liveDocs.get(iterator.docId))" is always false. I
think we should use the "hardLiveDocs" of a segment reader here instead. I
will open an issue and PR for this.

Cheers,
Nhat
