Elastic Search - Field weight (for boosting) in mapping

I know we can boost a field like this while making a search query in Elastic Search. Can we do this in mapping by giving a field extra weight?

GET /_search
{
    "query": {
        "function_score": {
            "field_value_factor": {
                "field": "likes",
                "factor": 1.2,
                "modifier": "sqrt",
                "missing": 1
            }
        }
    }
}

Index time boosting boosting is deprecated in ElasticSearch 5.x and not suggested anymore.

If you want boosting just do it in search time.

Yes, you can do that using the boost setting in your field declaration:

PUT my_index
{
  "mappings": {
    "_doc": {
      "properties": {
        "likes": {
          "type": "integer",
          "boost": 1.2                  <--- add this
        }
      }
    }
  }
}
