title: Elasticsearch - set max_clause_count
body: <p>I have a pretty big terms query in elasticsearch, so I get 
  <code>too_many_clauses: maxClauseCount is set to 1024</code></p>
  
  <p>I tried increasing it in the elasticsearch.yml by</p>
  
  <pre><code>index:
  query:
  bool:
  max_clause_count: 10240
  </code></pre>
  
  <p>and via </p>
  
  <pre><code>curl -XPUT "http://localhost:9200/plastic/_settings" -d '{ "index" : { "max_clause_count" : 10000 } }'
  </code></pre>
  
  <p>but nothing worked. My index is named plastic.</p>
