Update only specific field value in elasticsearch

As a codebased contribution to this answer, the following query may be used:

POST /index/type/100100471/_update
{
    "doc" : {
        "yourProperty" : 10000
    }
}

This query updates yourProperty property only.

As a result, this response appears:

{
   "_index": "index",
   "_type": "type",
   "_id": "100100471",
   "_version": 1,
   "_shards": {
      "total": 0,
      "successful": 1,
      "failed": 0
   }
}
