[0.9.11] simple_query_string does not recognize fields by their nested name but only by index_name

[roytmana]

{
  simple_query_string: {
    query: 'hello world',
    fields:['award.title']
  }
}

returns no results while

{
  simple_query_string: {
    query: 'hello world',
    fields:['award_title']
  }
}

returns expected results. the issue is with fields:[] in first case I use logical (dot-notation) field name while ion the second I use actual lucene name (index_name in the mappings below)

"award": {
  "properties":{
            "title": {
              "type": "multi_field",
              "path": "just_name",
              "fields": {
                "title": {
                  "type": "string",
                  "index_analyzer": "stemmed",
                  "search_analyzer": "stemmed",
                  "index_options": "offsets",
                  "index_name": "award_title",
                  "boost": 3
                },
                "all": {
                  "type": "string",
                  "index_name": "i_all",
                  "boost": 3
                },
                "all_shingle": {
                  "type": "string",
                  "analyzer": "not_stemmed_shingle",
                  "index_name": "i_all_shingle",
                  "boost": 3
                },
                "all_stem": {
                  "type": "string",
                  "index_analyzer": "stemmed",
                  "search_analyzer": "stemmed",
                  "index_name": "i_all_stem",
                  "boost": 3
                }
              }
            }
...
  }
}

I'm guessing this is because XSimpleQueryParser uses Lucene's query creators, and Lucene doesn't resolve the field using the mapping (just a guess). I'll take a look at this.
