> Today we carry over hard deletes based on the SegmentReaders liveDocs.
> This is not correct if soft-deletes are used especially with rentention
> policies. If a soft delete is added while a segment is merged the document
> might end up hard deleted in the target segment. This isn't necessarily a
> correctness issue but causes unnecessary writes of hard-deletes. The
> biggest
> issue here is that we assert that previously deleted documents are still
> deleted
> in the live-docs we apply and that might be violated by the retention
> policy.
