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"} },
                { "term" : { "_type" : {"value" : "foo", "boost" : 2.0} } }
            ]
        }
    }
}'


# faster option, use custom filters score, since the _type filter can be heavily
# cached, and boosting has more fine grained control
curl -XGET 'http://localhost:9200/twitter/_search?pretty=1' -d '{
    "query" : {
        "custom_filters_score" : {
            "query" : {
                "text" : { "message" : "hello" }
            },
            "filters" : [
                {
                    "filter" : { "term" : {"_type" : "foo"} },
                    "boost" : 2
                }
            ]
        }
    }

After looking for a while on how to boost a specific index type I found this gist, but I'm wondering how can I make it work in ES 5.6?
