万一它对任何人都有帮助，这就是我最近实施加权改组的方式。

在此示例中，我们对公司进行了洗牌。每个公司都有一个介于0到100之间的“
company_score”。通过这种简单的加权改组，得分为100的公司出现在首页的可能性是得分为20的公司的5倍。

json_body = {
    "sort": ["_score"],
    "query": {
        "function_score": {
            "query": main_query,  # put your main query here
            "functions": [
                {
                    "random_score": {},
                },
                {
                    "field_value_factor": {
                        "field": "company_score",
                        "modifier": "none",
                        "missing": 0,
                    }
                }
            ],
            # How to combine the result of the two functions 'random_score' and 'field_value_factor'.
            # This way, on average the combined _score of a company having score 100 will be 5 times as much
            # as the combined _score of a company having score 20, and thus will be 5 times more likely
            # to appear on first page.
            "score_mode": "multiply",
            # How to combine the result of function_score with the original _score from the query.
            # We overwrite it as our combined _score (random x company_score) is all we need.
            "boost_mode": "replace",
        }
    }
}
