Friends:

I have the following document a structural hierarchy, indexed.

```
{  
   "id":"abc",
   "nodeCount":12,
   "edgeCount":11,
   "degreesCountMap":[  
      {  
         "size":2,
         "count":10
      },
      {  
         "size":3,
         "count":2
      }
   ]
}

```

Then I ran the query:

```
{  
   "query":{  
      "bool":{  
         "must":[  
            {  
               "range":{  
                  "degreesCountMap.size":{  
                     "from":3
                  },
                  "degreesCountMap.count":{  
                     "from":10
                  }
               }
            }
         ]
      }
   }
}

```

Expected a no match because I thought ES will try to match `{"size":3,"count":2}` or `{"size":2,"count":10}` however, the document was matched. I assume it matched **size:3** from `{"size":3,"count":2}` and **count:10** from another `{"size":2,"count":10}`. My question: Is there a way to force the match to happen with one `{...}`.

I have also tried the query below and found the same result:

```
{  
   "query":{  
      "bool":{  
         "must":[  
            {  
               "range":{  
                  "degreesCountMap.size":{  
                     "from":3
                  }
               }
            },
            {  
               "range":{  
                  "degreesCountMap.count":{  
                     "from":10
                  }
               }
            }
         ]
      }
   }
}

```

I will appreciate your help.

Elasticsearch/Lucene will bunch each inner field into the same bucket  
causing the behavior you noticed. You would need to define each inner  
object as a nested object [1] and use a nested query [2] to limit the query  
on a single nested document.

See

Ivan:

Thanks for your reply. As I mentioned I did find the information I was looking for at [Managing Relations Inside Elasticsearch](https://www.elastic.co/blog/managing-relations-inside-elasticsearch).
