ElasticSearch: search inside the array of objects

For search multiple terms use the Terms query instead of Term query.

"terms" : {
        "tags" : [ "turkey", "mugla-province" ],
        "minimum_should_match" : 1
    }

There are various ways to construct this query, but this is the simplest and most elegant in the current version of ElasticSearch (1.6)

Here's one way you can do it, using nested docs:

I defined an index like this:

PUT /test_index
{
   "mappings": {
      "doc": {
         "properties": {
            "parent": {
               "type": "nested",
               "properties": {
                  "label": {
                     "type": "string"
                  },
                  "name": {
                     "type": "string"
                  }
               }
            }
         }
      }
   }
}

Indexed your document:

PUT /test_index/doc/1
{
   "parent": [
      {
         "name": "turkey",
         "label": "Turkey"
      },
      {
         "name": "turkey,mugla-province",
         "label": "Mugla (province)"
      }
   ]
}

Then either of these queries will return it:

POST /test_index/_search
{
    "query": {
        "nested": {
           "path": "parent",
           "query": {
               "match": {
                  "parent.name": "turkey"
               }
           }
        }
    }
}

POST /test_index/_search
{
    "query": {
        "nested": {
           "path": "parent",
           "query": {
               "match": {
                  "parent.name": "turkey,mugla-province"
               }
           }
        }
    }
}

Here's the code I used:
