ElasticSearch: How to specify specific fields to search at? -

right in mapping, setting "include_in_all" true, means fields included in _all field.

however, when searching, instead of wasting space, , putting in _all field, want specify specific fields (and taking account boost scores in mapping).

how create query tells elastic search @ specific fields(not 1) , take account boosting gave during mapping?

start multi_match query. allows query multiple fields, giving them different weights, , it's way go when have search box.

{   "multi_match" : {     "query" : "this test",     "fields" : [ "subject^2", "message" ]   } } 

the query_string more powerful more dangerous since it's parsed , can break. use if need it.
