Tim Smith commented on LUCENE-1721:
-----------------------------------
Looks like its actually a SegmentReader
old index: org.apache.lucene.index.segmentrea...@f38cf0
new index: org.apache.lucene.index.segmentrea...@7bfc04
i guess that in 2.4, if you have an optimized index, and you call reopen(), you
will always get a new SegmentReader instance (so the == check isn't really
valid)
i guess this is a non-issue in 2.9 (opened index is never a SegmentReader, even
in the optimized case)
> IndexWriter to allow deletion by doc ids
> ----------------------------------------

> Key: LUCENE-1721
> URL: https://issues.apache.org/jira/browse/LUCENE-1721
> Project: Lucene - Java
> Issue Type: Improvement
> Components: Index

> It would be great if IndexWriter would allow for deletion by doc ids as well.
> It makes sense for cases where a "query" has been executed beforehand, and
> later, that query needs to be applied in order to delete the matched
> documents.
