Algorithm complexity

Elastic Stack Elasticsearch
1

What is the Algorithm (time) complexity of the search function / algorithm
in Elastic Search? I was just wondering for my information.

Is there a place where I can find this and other facts about Elastic Search
?

First of all something like a hash table or a reverse index ( in simple
words) powers the search of ES.
Lucene library does this part.
So theoretically , the search complexity should be O(1).

I know it is lucene. But is it a hash table or reverse index?
