How to query against nested attributes where the attribute name has a space in it

Elastic Stack Elasticsearch
#1

When doing a term query on nested documents with spaces, what is the correct syntax? My document looks like this:
{
"details": {
"first name": "jim"
}
}

I have a bool query where we are trying to match documents with a first name of jim, but it is returning no documents. This is what I've tried:

{"bool":{"must":[{"term":{"details.first name":"jim"}}]}}

What is the right way to be querying against nested fields with a space in the field name?

Hi,

there is nothing special about spaces. This works fine with Elasticsearch 2.3:

PUT /company
{
   "mappings": {
      "employee": {
         "properties": {
            "name": {
               "type": "object",
               "properties": {
                   "first name": {
                       "type": "string",
                       "index": "not_analyzed"
                       
                   },
                   "last name": {
                       "type": "string",
                       "index": "not_analyzed"
                   }
               }
            }
         }
      }
   }
}

POST /company/employee/1
{
   "name": {
      "first name": "Steve",
      "last name": "Jobs"
   }
}

GET /company/employee/_search
{
    "query": {
        "term": {
           "name.first name": {
              "value": "Steve"
           }
        }
    }
}

The search returns:

{
   "took": 30,
   "timed_out": false,
   "_shards": {
      "total": 5,
      "successful": 5,
      "failed": 0
   },
   "hits": {
      "total": 1,
      "max_score": 0.30685282,
      "hits": [
         {
            "_index": "company",
            "_type": "employee",
            "_id": "1",
            "_score": 0.30685282,
            "_source": {
               "name": {
                  "first name": "Steve",
                  "last name": "Jobs"
               }
            }
         }
      ]
   }
}
