Boosting queries by type

James_Wilson · October 18, 2011, 6:23pm

Suppose I am searching using a text query (or query_string, field,
etc.) and would like to boost any results where a document field has a
specific value (in particular, _type). How can I express this in the
query DSL?

I gisted two options that you can use, one using bool query (with should
clauses), and one using custom_filters_score (preferable):

gistfile1.sh

curl -XPUT http://localhost:9200/twitter/foo/1 -d '{"message": "hello world"}'
curl -XPUT http://localhost:9200/twitter/bar/1 -d '{"message": "hello world"}'

# Use bool query with should clause, which ends up aggregating the scores if matching
# several clauses
curl -XGET 'http://localhost:9200/twitter/_search?pretty=1' -d '{
    "query" : {
        "bool" : {
            "should" : [
                { "text" : { "message" : "hello"} },

preferable in terms of performance?
