Description
Chatting with Adrien Grand , 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.
