Indexing indexing multi_field with array field

Question

I am new to elasticsearch and I am trying to create a multi_field index with stringand fields array of strings. stringEverything works fine with fields , but when I try to get some results when they are inside the array, it returns empty.

My details:

{
  "string_field_one": "one",
  "string_field_two": "two",
  "array_of_strings_field": [
     "2010", "2011", "2012", "2013"
  ]
}

Display:

{
    "string_field_one" : {
        "type" : "string",
        "analyzer": "snowball",
         "copy_to": "group"
     },
    "string_field_two" : {
        "type" : "string",
        "analyzer": "snowball",
         "copy_to": "group"
     },
    "array_of_strings_field" : {
         "type" : "string",
         "analyzer": "keyword",
         "copy_to": "group"
    }
    "group" : {
        "type": "multi_field"
    }
}

Search:

 "body": {
          "query": {
              "multi_match": {
                  "query": "one two 2010",
                  type: "cross_fields",
                  operator: "and",
                  fields: [
                      "string_field_one",
                      "string_field_two",
                      "array_of_strings_field",
                      "group"
                  ]
              }
          }
      }

Expecting:

• Search by one, twoor 2010should return a result
• Search one twoshould return a result
• Search one two 2010should return a result
• Search one two 2008should not return a result

What am I missing?
