Sorry if i am wrong

Why didn't you use keyword since you need exact matching text . like below:


GET autocomplete_test/_search
{
  "query": {
    "match": {
      "doc1.keyword": "hero"
    }
  }
}

Output

{
  "took" : 0,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 1,
      "relation" : "eq"
    },
    "max_score" : 0.9808292,
    "hits" : [
      {
        "_index" : "autocomplete_test",
        "_type" : "_doc",
        "_id" : "3",
        "_score" : 0.9808292,
        "_source" : {
          "doc1" : "hero"
        }
      }
    ]
  }
}

This feature made for auto complete

"Hero" is result we want
Is we serch

H :Doc1,Doc2,Doc3
He :Doc1,Doc2,Doc3
Her : Doc1,Doc2,Doc3
Hero : Doc1,Doc2,Doc3

But we need only "Hero":Doc3

We not sure we need how to implement by Regexp query or script Regexp query
