当我尝试向我的Elasticsearch发出query_string请求时,它使用function_score(script_score
)来操纵其默认分数。但我似乎总是得到_score
的基础1.0
。
我的型号如下所示:
{
"name": "Secret Birthday Party",
"description": "SECRET! Discuss with discretion",
"_userCounters": [
{
"user": "king",
"count": 12
},
{
"user": "joseph",
"count": 1
}
]
}
使用function_score脚本的请求如下所示:
{
"query" : {
"function_score" : {
"query": {
"query_string": {
"query": "secret",
"analyze_wildcard": true,
"fields": [
"name", "description"
]
}
},
"script_score": {
"script": {
"inline" : "int scoreBoost = 1; for (int i = 0; i < params['_source']['_userCounters'].length; i++) { if (params['_source']['_userCounters'][i].user == 'joseph') { scoreBoost += params['_source']['_userCounters'][i].count; } } return scoreBoost;"
}
}
}
}
}
我得到的结果是找到我想要的结果,但只返回function_score脚本中的值。内置评分似乎不再起作用了。这是我得到的回复:
{
"_index": "test3",
"_type": "projects",
"_id": "7",
"_score": 2, // this is exactly the return value of the script_score. What I want instead is that this value gets multiplied with the normal score of ES
"_source": {
"name": "Secret Birthday Party",
"description": "SECRET! Discuss with discretion",
"_userCounters": [
{
"user": "queen",
"count": 12
},
{
"user": "daniel",
"count": 1
}
]
}
}
我的猜测是我的请求正文格式不正确,因为当我完全取出function_score时,所有得分都只是1.0
。
答案 0 :(得分:0)
我明白了。这实际上是脚本本身的问题,而不是请求体的结构。
该函数仅返回因子,该因子应该与expandedRowKeys={this.state.expandedKeys}
值相乘。相反,它需要自己进行乘法运算。
这是一个比较简单的脚本:
