title: Elasticsearch Nested-field vs Depth? Check for document depth via Kibana?
body: <p>I'm reading about mapping in <a href="https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping.html#mapping-limit-settings" rel="nofollow noreferrer">elasticsearch</a> and I see these 2 terms: Nested-field &amp; Depth. I think these 2 terms are quite equivalent. I'm currently confused by these 2. Please can anyone clear me out? Thank you.
  And btw, are there any ways to check a document depth via Kibana?</p>
  <p>Sorry for my english.</p>
