Hello everyone,  
Hope you are doing good.

How does elasticsearch clauses of a query? Which it eventually compares with `max_clause_count` and throws an RuntimeException if query exceeds maxClauseCount.

I understand how it calculates max\_clause\_count dynamically using `heapInMb` and `threadPoolSize`. But how does it calculates for a query that part is unclear?

I think the code reference - `org.apache.lucene.search.MultiTermQuery.RewriteMethod#collectTerms`
