Type order in multi-type query affects query results?

I'm running ES 1.7.1 on found, accessing it via the Java client (1.7.1).

I've found that the order of the types I define in the query changes the results. For instance, if I use types 'a,b,c', I get different results from 'b,c,a'. E.g.

This is the query I used:

{
  "from" : 0,
  "size" : 28,
  "query" : {
    "filtered" : {
          "query" : {
            "bool" : {
              "should" : {
                "multi_match" : {
                  "query" : "alan",
                  "fields" : [ "name^2", "nickName^2", "role^1.5", "localization" ],
                  "fuzziness" : "AUTO"
                }
              }
            }
          },
          "filter" : {
            "bool" : {
              "must" : [ {
                "type" : {
                  "value" : "person"
                }
              }, {
                "range" : {
                  "createdOn" : {
                    "from" : null,
                    "to" : 1450291614644,
                    "include_lower" : true,
                    "include_upper" : true
                  }
                }
              }, {
                "missing" : {
                  "field" : "deletedOn"
                }
              } ]
            }
          }
        }     
  }
}

If I run GET ciandt-com/person,linkPost,post/_search, I get one result, as expected:

{
   "took": 1,
   "timed_out": false,
   "_shards": {
      "total": 1,
      "successful": 1,
      "failed": 0
   },
   "hits": {
      "total": 1,
      "max_score": 4.6976204,
      "hits": [
         {
            "_index": "ciandt-com-20151216183428244",
            "_type": "person",
            "_id": "635181261",
            "_score": 4.6976204,
            "_source": {
               "type": "person",
               "avatar": {
                  "url": "https://lh5.googleusercontent.com/-qpD-rFV18pA/AAAAAAAAAAI/AAAAAAAAAr8/ZbnMNmGxH8w/photo.jpg"
               },
               "cover": {
                  "url": "https://lh5.googleusercontent.com/-qpD-rFV18pA/AAAAAAAAAAI/AAAAAAAAAr8/ZbnMNmGxH8w/photo.jpg"
               },
               "createdOn": "2015-12-16T18:04:34.173Z",
               "email": "alanbk@ciandt.com",
               "hashtags": [],
               "id": 635181261,
               "name": "Alan Kleiman",
               "nickName": "mars",
               "phone": "",
               "title": "Alan Kleiman",
               "universalId": "PersonProfile:alanbk@ciandt.com"
            }
         }
      ]
   }
}

But if I run GET ciandt-com/linkPost,person,post/_search:

{
   "took": 1,
   "timed_out": false,
   "_shards": {
      "total": 1,
      "successful": 1,
      "failed": 0
   },
   "hits": {
      "total": 0,
      "max_score": null,
      "hits": []
   }
}

Am I missing something here?

Edit: Fussing with the query some more, I removed the type query, and this behavior disappeared. Should I just not use the type query?

was there any resolution to this question ?

Thanks
