Boosting a has_child in a bool query

David_Hagar · February 12, 2013, 2:16am

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' -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' -d '{

"bodyText" : "Creativity is inteligence having fun - Albert Einstein"

}'

curl -XPUT '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' -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
}
}
}'

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.

Yes, just write it as:

{ has_child: {
boost: 2,
...

curl -XPUT 'http://localhost:9200/collection-test?pretty=true' -d '{
"settings" : {

},
"mappings" : {

    "document": {
        "properties": {
            "bodyText": { "type": "string" }
        }
    },
 
    "collection_item": {

            "collection_id": { "type": "integer", "index":
"not_analyzed" }

curl -XPUT 'http://localhost:9200/collection-test/document/1' -d '{

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.
