Field names with dot notation in ES Node.js client

[Cholley_Alexandre]

Hi, I'm trying to write a field with dot notation in the body of the Search API in Node.js Client but it doesn't work.

The mapping is :

"my_field": {
    "type":"text",
    "fields": {
      "keyword": {
        "type": "keyword"
      } 
    }
  }

I tried :

query: {
    bool: {
      must: {
        term: my_field.keyword: my_value
      }
    }
}

query: {
    bool: {
      must: {
        term: "my_field.keyword": my_value
      }
    }
}

query: {
    bool: {
      must: {
        term: {
          my_field: {
            keyword: my_value
          }
        }
      }
    }
}

query: {
    bool: {
      must: {
        term: {
          my_field: {
              fields: {
                  keyword: my_value
              }
          }
        }
      }
    }
}

It's throws a parsing error from Elasticsearch.

Thank you in advance for your help

After several tests on Node.js client, it works using JSON Object Notation for entirely body (all field names and values double quoted) instead of a common object notation. In the documentation it's mentioned :

body : object - The search definition using the Query DSL

and the example show a common object notation but not a JSON Object notation in the body field. I suppose that works because the requests need to be send to elasticsearch with application/json content-type and the parser work to do that.

"query": {
    "bool": {
      "must": {
        "term": "my_field.keyword": "my_value"
      }
    }
}

Could someone confirm that it's a correct way please ?

Thank you in advance.
