This only captures when there is Lucene major version discrepancy. The
check()
method can be updated later to cope with internal index changes.I had to add Lucene backward codecs so that the segment file can actually be opened. Otherwise it will result in
IllegalArgumentException
as noted in the issue.For now no data deletion is done, this is up to the user.
