Sorry for the noob question, but I seem to have a disconnect when it  
comes to mapping and boost values. Currently I use field level  
boosting in my mapping file like so

```
    "option.Antibody Products" : {
      "type" : "multi_field",
      "fields" : {
        "option.Antibody Products" : {
          "include_in_all" : true,
          "boost" : 4.0,
          "type" : "string"
        },
        "stored" : {
          "include_in_all" : false,
          "store" : "yes",
          "analyzer" : "lowercase_whitespace",
          "type" : "string"
        }
      }

```

and for that I have to manually go in and update the boost value in  
the mapping file. Is there a way I can update this value when I index  
the document? I've checked [http://www.elasticsearch.org/guide/reference/mapping/boost-field.html](http://www.elasticsearch.org/guide/reference/mapping/boost-field.html)  
but it seems to be updating the boost value of the document and not  
the individual fields.

Thanks for any and all help

You can provide a custom boost value within the json, shown here (check at  
the end of the string section):  
[Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/mapping/core-types.html). Note  
though, it will not work with multi field mapping sadly...
