title: Elasticsearch global search different filter on multiple indexes
body: <p>We have got multiple indices in Elastic Search and would like to search the data across all indices, but we want to apply different filters on different indices.</p>
  
  <p>For example:</p>
  
  <ul>
  <li>few indices depends on <code>client_id</code>, hence a <code>client_id</code> filter is required</li>
  <li>we have <code>is_deleted</code> flag in few indexes, hence <code>is_deleted</code> filter is required</li>
  </ul>
  
  <p>How should one approach this in Elastic Search?</p>
  
  <p>Also, we are using highlight feature, which is supposed to give suggestions to the users. But we would like to ignore certain fields in the highlighted results. Is it possible to exclude certain fields at global level?</p>
