Description

### Description

Hi, recently I read a [paper](https://www.vldb.org/pvldb/vol15/p3472-yu.pdf) from [VLDB](https://vldb.org/2022/?paper-session) said it gains significant performance improvements against Lucene. It achieves 20x performance increase with standard queries, and 10x performance increase with histogram queries in massive log query scenarios.

After read the whole content, it seems that the core idea in this paper is similar to `IndexSortSortedNumericDocValuesRangeQuery`, dose someone have free time to read this paper and have a discussion here?

Research direction

Start by reading the linked VLDB paper and comparing its core idea with Lucene's IndexSortSortedNumericDocValuesRangeQuery. The issue does not name files, tests, or a specific change; a useful next step would be to define a concrete optimization scope and an evaluation plan for standard and histogram queries.

Written by the indexing model from the issue text.
