> 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.
