-----------------------------------
Summary: Make IndexRearranger able to arrange segment into a
determined order
Key: LUCENE-10371
URL: https://issues.apache.org/jira/browse/LUCENE-10371
Project: Lucene - Core
Issue Type: Improvement
Reporter: Haoyu Zhai
Previously when I tried to make change to luceneutil to let it use
{{IndexRearranger}} for a faster deterministic index construction, I found that
even each segment contains the same documents set, the order of segments will
impact the estimated hit number (using BMW):
[https://markmail.org/message/zl6zsqvbg7nwfq6w]
At that time the discussion tend to tolerant the small hit count difference to
resolve the issue, after some time when I discuss this issue again with
[~mikemccand] , we thought it might also be a good idea to just add ability of
rearranging the segments order to {{IndexRearranger}}, so that we can ensure
each time the rearranged index is truly the same.
