title: Why is their a limit on max number of clauses in bool query in elasticsearch
body: <p>I want to know that why there is a limit on max clauses in a bool query that is <strong>1024</strong>
  <strong>indices.query.bool.max_clause_count : 1024</strong>.</p>
  
  <p>Also is it ok if an OR query is fired with say <strong>1 million terms</strong> in a bool query?</p>
