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",
}
}
}
