请问一下，如何将评论和销量转化为搜索相关性打分项

Script Based Sortingedit

Allow to sort based on custom scripts, here is an example:



GET /_search

{

    "query" : {

        "term" : { "user" : "kimchy" }

    },

    "sort" : {

        "_script" : {

            "type" : "number",

            "script" : {

                "lang": "painless",

                "source": "doc['field_name'].value * params.factor",

                "params" : {

                    "factor" : 1.1

                }

            },

            "order" : "asc"

        }

    }

}
