How can I use ElasticSearch term queries to filter for a value in an array of objects?-CodePudding

I'm attempting to send a POST req to an API so that I only receive hits with role: "editor". The unfiltered response looks like:

_source: {
  configuration: {
    roles : [
        {role : "lead"},
        {role : "editor"},
      ]
  }
}

I'm attempting to use the following query to receive the desired response:

body: {
  size: 10,
  query: {
    bool: {
      must: { 
        term: {
          role : "editor"
        }
      }
    }
  }
}

But I receive 0 hits even though I can verify there are thousands of hits with role: "editor".

I've also tried variations of this request with:

body: {
  size: 10,
  query: {
    bool: {
      must: { 
        term: {
          "roles.role" : "editor"
        }
      }
    }
  }
}

body: {
  size: 10,
  query: {
    bool: {
      must: { 
        term: {
          "roles" : "role.editor"
        }
      }
    }
  }
}

Does anyone know what I'm doing incorrectly? It seems like the problem is that Roles is an array of objects and I'm not accessing the role value corectly.

CodePudding user response：

If you field "roles" is nested type you must use Nested Query.

{
  "query": {
    "nested": {
      "path": "roles",
      "query": {
        "term": {
          "roles.role": {
            "value": "editor"
          }
        }
      }
    }
  }
}

If not "nested", try this:

{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "roles.role": {
              "value": "lead"
            }
          }
        }
      ]
    }
  }
}
