How to alphabetically sort a name field in Elasticsearch?

Question

I have the following definition for the name field:

"name": {
  "type": "text",
  "fields": {
    "keyword": {
      "type": "keyword",
      "ignore_above": 256
    }
  }
},

How do I sort this alphabetically ?

I am trying the following

{
  "query": {
    "match": {
      "name": "Shoes"
    }
  },
  "sort": {
    "keyword": {
       "order": "asc"
    }  
  },
  "size": 10,
  "from": 0,
  "sort": []
}

But the sort somehow doesn't seem to be doing anything at all.

I have referred to these threads but they doesn't seem to help in my case.

You need to refer to the name.keyword subfield and also you have two different sort sections in your search, remove the empty one:

{
  "query": {
    "match": {
      "name": "Shoes"
    }
  },
  "sort": {
    "name.keyword": {         <---- change this
       "order": "asc"
    }  
  },
  "size": 10,
  "from": 0,
  "sort": []                  <---- remove this
}
