title: Kibana does not search on nested field
body: <p>working with Elasticsearch/Kibana and trying to search on field in a nested object. However it does not seem to work. Here's mapping that I use in a template:</p>

  <p>When I do search kibana on single fields - everything works fine. Still though i cannot search on nested fields like 'nested.name'.</p>
  
  <p>Example of my query in kibana: nested.name:hi</p>
  
  <p>Thanks.</p>
