Suggestion field not updated

[jenson.mak (Jen Son)]

I have a problem where the elastic search is providing autocomplete suggestion for value which I already remove in the index field. For example, previously I have field ARR:. TEST in talents.name field. I have updated the record and ARR:. TEST is no longer in talents.name. However, when I query _suggest,

{"complete" :{ "text" : "ARR:. TEST", "completion" : { "field" : "talents_suggest", "size" : 20 }}}

the record still appear as below result.

{

* "_shards": {
  * "total": 5,
  * "successful": 5,
  * "failed": 0},
* "complete": [
  * {
    * "text": "ARR:. TEST",
    * "offset": 0,
    * "length": 17,
    * "options": [
      * {
        * "text": "ARR.-TEST",
        * "score": 3}
,      * {
        * "text": "ARR.: TEST",
        * "score": 3}
,      * {
        * "text": "ARR: TEST",
        * "score": 3}]}]

} 

I tried query talents_suggest field directly, and there's result returned, but I can't see talents_suggest field in the json returned. How do I verify, that ARR.: TEST is still existing in talents_suggest or not ?

{
"query": {
"match": {
"talents_suggest": {
"query": "ARR.: TEST"
}
}
}
}

I am using elastic search v1.4.

The mapping I used is

 "talents": {
            "type" : "nested",
            "properties": {
                "type": {
                    "type": "string", 
                    "index" : "not_analyzed"
                },
                "name": {
                    "type": "string",
                    "analyzer": "char_analyzer",
                    "copy_to": ["common_suggest", "talents_suggest"],
                    "fields": {
                        "raw": { 
                            "type": "string", 
                            "analyzer": "case_insensitive_sort"
                        }
                    }
                }
            }
    	},
