Can you boost a has\_child query inside of a bool query? Here is my example. There are multiple has\_child queries each of which represent a collection that contains documents. Mapping curl -XPUT '[http://localhost:9200/collection-test?pretty=true](http://localhost:9200/collection-test?pretty=true)' -d '{ ``` "settings" : { "number_of_shards" : 1, "number_of_replicas" : 0 }, "mappings" : { "document": { "properties": { "bodyText": { "type": "string" } } }, "collection_item": { "_parent": { "type": "document" }, "_all" : {"enabled" : false}, "properties": { "collection_id": { "type": "integer", "index": ``` "not\_analyzed" } } } ``` } ``` }' Documents curl -XPUT '[http://localhost:9200/collection-test/document/1](http://localhost:9200/collection-test/document/1)' -d '{ ``` "bodyText" : "Creativity is inteligence having fun - Albert Einstein" ``` }' curl -XPUT '[http://localhost:9200/collection-test/document/2](http://localhost:9200/collection-test/document/2)' -d '{ ``` "bodyText" : "Anything one man can imagine, other men can make real. - ``` Jules Verne" }' curl -XPUT '[http://localhost:9200/collection-test/document/3](http://localhost:9200/collection-test/document/3)' -d '{ ``` "bodyText" : "Man will become better when you show him what he is like. ``` - Anton Chekhov" }' Collections curl -XPOST localhost:9200/collection-test/collection\_item/1?parent=1 -d '{ "collection\_id" : "1" }' curl -XPOST localhost:9200/collection-test/collection\_item/2?parent=1 -d '{ "collection\_id" : "2" }' curl -XPOST localhost:9200/collection-test/collection\_item/4?parent=2 -d '{ "collection\_id" : "2" }' Multiple Term and Multiple Collection Query Note: running this query requires at least ES 0.20.2 to support "score\_type". curl -XPOST localhost:9200/collection-test/document/\_search?pretty=true -d '{ "query" : { "bool" : { "should" : [ { "term" : { "bodyText" : { "value" : "inteligence", "boost" : 1.0 } } }, { "term" : { "bodyText" : { "value" : "anything", "boost" : 1.0 }} }, { "has\_child" : { "type" : "collection\_item", "score\_type" : "sum", "query" : { "term" : { "collection\_id" : "1" } } } }, { "has\_child" : { "type" : "collection\_item", "score\_type" : "sum", "query" : { "term" : { "collection\_id" : "2" } } } } ], "minimum\_number\_should\_match" : 1 } } }' -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Many thanks. Adding a boost field works. You are the only one here answering my questions so far 🙂 . The documentation for has\_child doesn't show a boost field. Is there a process for updating it?

FYI, every query type supports a boost. Also, I have completely documented every query, filter, and facet while implementing Elastic.js. These docs can be useful even when using the RESP api, especially if you use them along with the query translator that converts the javascript to the REST version of the request.
