Luca Cavanna commented on LUCENE-8796:
--------------------------------------

You are right [~ysee...@gmail.com] I will make that change and re-run 
benchmarks.

> Use exponential search in IntArrayDocIdSet advance method

>                 URL: https://issues.apache.org/jira/browse/LUCENE-8796
>             Project: Lucene - Core
>          Issue Type: Improvement
>            Reporter: Luca Cavanna
>            Priority: Minor
>
> Chatting with [~jpountz] , he suggested to improve IntArrayDocIdSet by making 
> its advance method use exponential search instead of binary search. This 
> should help performance of queries including conjunctions: given that 
> ConjunctionDISI uses leap frog, it advances through doc ids in small steps, 
> hence exponential search should be faster when advancing on average compared 
> to binary search.
