Elasticsearch the terms filter raise "filter does not support [mediatest]"

Question

my query is like this:

{
  "query": {
    "filtered": {
      "filter": {
        "bool": {
          "must": [
            {
              "term": {
                "online": 1
              }
            },
            {
              "terms": {
                "mediaType": "flash"
              }
            }
          ]
        }
      }
    }
  }
}

it raise a QueryParsingException [[comos_v2] [terms] filter does not support [mediaType]],of which the field "mediaType" exactly does not exist in mapping. my question is why term filter does not raise the Exception?

Answer 1

The above is not a valid Query DSL. In the above Terms filter the values to "mediaType" field should be an array

It should be the following :

{
  "query": {
    "filtered": {
      "filter": {
        "bool": {
          "must": [
            {
              "term": {
                "online": 1
              }
            },
            {
              "terms": {
                "mediaType": ["flash"]
              }
            }
          ]
        }
      }
    }
  }
}

Its 2021 I'm using .keyword for an exact text match but you can just as easily omit:

{"query":
  {"bool":
    {"must":
      [
        {"term":
          {"variable1.keyword":var1Here}
        },
        {"term":
          {"variable2.keyword":var2Here}
        }
      ]
    }
  }
}
