Description
In log scenario, we usually want to know the doc count of documents between every time intervals. One possible optimized method is to sort the docuemt in ascend order according to @timestamp field in one segment. then we can use this pr https://github.com/apache/lucene/pull/687 to find out the min/max docId in on time interval.
If there is no other filter query, the doc count of one time interval is (max docId- min docId +1)
if there is only one another term filter query, we can use this pr https://github.com/apache/lucene/pull/688 to get the diff value of index, when we call advance(minId) and advance(maxId), the diff value is also the doc count of one time interval
