ElasticSearch-“没有注册查询...”

Question

ElasticSearch returns me "No query registered for [likes_count]" error when trying to look up entries using the following query. The field likes_count is a new field of documents and does not exist in every document.

The same query works without the sort part.

Why does this error appear?

Thanks

{
  "query": {
    "filtered": {
      "query": {
        "query_string": {
          "fields": ["description"],
          "query": "sun"
        },
        "sort": [{
          "likes_count": {
            "unmapped_type": "boolean",
            "order": "desc",
            "missing": "_last"
          }
        }]
      },
      "filter": {"term": {"permissions": 1}}
    }
  }
}

Answer 1

Write your query like this, ie sort needs to go to the top-level and not nested in the query part:

{
  "query": {
    "filtered": {
      "query": {
        "query_string": {
          "fields": [
            "description"
          ],
          "query": "sun"
        }
      },
      "filter": {
        "term": {
          "permissions": 1
        }
      }
    }
  },
  "sort": [
    {
      "likes_count": {
        "unmapped_type": "boolean",
        "order": "desc",
        "missing": "_last"
      }
    }
  ]
}
