LUCENE-8796: Use exponential search in IntArrayDocIdSetIterator#advance (#667)
> Use exponential search in IntArrayDocIdSet advance method
> ---------------------------------------------------------
>
> Key: LUCENE-8796
> URL: https://issues.apache.org/jira/browse/LUCENE-8796
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Luca Cavanna
> Priority: Minor
> Time Spent: 50m
> Remaining Estimate: 0h
>
> 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.
