[jira] [Created] (LUCENE-3575) Field names can be wrong for stored
fields / term vectors after merging
Field names can be wrong for stored fields / term vectors after merging
-----------------------------------------------------------------------
Key: LUCENE-3575
URL: https://issues.apache.org/jira/browse/LUCENE-3575
Project: Lucene - Java
Issue Type: Bug
Affects Versions: 4.0
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: 4.0
The good news is this bug only exists in trunk... the bad news is it's
been here for some time (created by accident in LUCENE-2881). But the
good news is it should strike fairly rarely.
SegmentMerger sometimes incorrectly thinks it can bulk-copy TVs/stored
fields when it cannot (because field numbers don't map to the same
names across segments).
I think it happens only with addIndexes, or indexes that have
pre-trunk segments, and then SM falsely thinks it can bulk-merge only
when the last field number has the same field name across segments.
