Multilingual queries in ElasticSearch

Question

Let's say we have the following mapping in ElasticSearch.

{
  "content": {
    "properties": {
      "id": {
        "type": "string",
        "index": "not_analyzed",
        "store": "yes"
      },
      "locale_container": {
        "type": "object",
        "properties": {
          "english": {
            "type": "object",
            "properties": {
              "title": {
                "type": "string",
                "index_analyzer": "english",
                "search_analyzer": "english",
                "index": "analyzed",
                "term_vector": "with_positions_offsets",
                "store": "yes"
              },
              "text": {
                "type": "string",
                "index_analyzer": "english",
                "search_analyzer": "english",
                "index": "analyzed",
                "term_vector": "with_positions_offsets",
                "store": "yes"
              }
            }
          },
          "german": {
            "type": "object",
            "properties": {
              "title": {
                "type": "string",
                "index_analyzer": "german",
                "search_analyzer": "german",
                "index": "analyzed",
                "term_vector": "with_positions_offsets",
                "store": "yes"
              },
              "text": {
                "type": "string",
                "index_analyzer": "german",
                "search_analyzer": "german",
                "index": "analyzed",
                "term_vector": "with_positions_offsets",
                "store": "yes"
              }
            }
          },
          "russian": {
            "type": "object",
            "properties": {
              "title": {
                "type": "string",
                "index_analyzer": "russian",
                "search_analyzer": "russian",
                "index": "analyzed",
                "term_vector": "with_positions_offsets",
                "store": "yes"
              },
              "text": {
                "type": "string",
                "index_analyzer": "russian",
                "search_analyzer": "russian",
                "index": "analyzed",
                "term_vector": "with_positions_offsets",
                "store": "yes"
              }
            }
          },
          "italian": {
            "type": "object",
            "properties": {
              "title": {
                "type": "string",
                "index_analyzer": "italian",
                "search_analyzer": "italian",
                "index": "analyzed",
                "term_vector": "with_positions_offsets",
                "store": "yes"
              },
              "text": {
                "type": "string",
                "index_analyzer": "italian",
                "search_analyzer": "italian",
                "index": "analyzed",
                "term_vector": "with_positions_offsets",
                "store": "yes"
              }
            }
          }
        }
      }
    }
  }
}

When a particular user queries the index, we can take her culture from her settings, i.e. we know which analyzer to use. How can we formulate a query which will search only "title" and "text" fields in her own language (let's say, German) and use German analyzer to tokenize the search query?
