Question

I am developing an application that uses elastic search, and in some case I want to make a search that according to term and locales. I am testing this on localhost

http://localhost:9200/index/type/_search

and parameters

query : {
                        wildcard : { "term" : "myterm*" }
                    },
                    filter : {
                        and : [
                            {
                                term : { "lang" : "en" }
                            },
                            {
                                term : { "translations.lang" : "tr" } //this is subdocument search
                            },
                        ]
                    }

Here is an example document:

{
    "_index": "twitter",
    "_type": "tweet",
    "_id": "5084151d2c6e5d5b11000008",
    "_score": null,
    "_source": {
      "lang": "en",
      "term": "photograph",
      "translations": [
        {
          "_id": "5084151d2c6e5d5b11000009",
          "lang": "tr",
          "translation": "fotoğraf",
          "score": "0",
          "createDate": "2012-10-21T15:30:37.994Z",
          "author": "anonymous"
        },
        {
          "_id": "50850346532b865c2000000a",
          "lang": "tr",
          "translation": "resim",
          "score": "0",
          "createDate": "2012-10-22T08:26:46.670Z",
          "author": "anonymous"
        }
      ],
      "author": "anonymous",
      "createDate": "2012-10-21T15:30:37.994Z"
    }
  }

I am trying to get terms with wildcard(for autocomplete) with input language “en”, and output language “tr”. It is getting terms that has “myterm” but doesnt apply, and operation on this. Any suggestion would be appreciated

Thanks in advance

I have manage to solve my problem with following query;

query : {
   wildcard : { "term" : "myterm*" }
},
filter : {
   and : [
      {
         term : { "lang" : "en" }
      },
      {
         term : { "translations.lang" : "tr" } //this is subdocument search
      }
   ]
},
sort : {
   {"term" : "desc"}
}

An important point here is, you need to set your sorting field as not_analyzed. Since, you cannot sort a field that is analyzed.
