Sivan Yogev updated LUCENE-4258:
--------------------------------
Attachment: LUCENE-4258.r1412262.patch
New patch with additional testing and bug fixes.
Currently the term statistics does not take into account field replacements,
and therefore term counts are wrong and CheckIndex fails.
I can think of two possible solutions for this. The first is for CheckIndex to
identify updated segments and ignore term statistics - is there similar
mechanism for deletions?
The other solution is to pre-compute term statistics for updated segments.
However, this will be costly - requires going through the entire posting list
for every term, and count non-replaced occurrences.
Any suggestions?
