elasticsearch 弹性搜索_聚合中的分数为空。为什么？
elasticsearch 弹性搜索_聚合中的分数为空。为什么？
我使用ESV1.7。ES只在“点击数”部分返回_分数，但我对“点击数”不感兴趣，我需要Response中带有_分数的“聚合”部分的数据。为什么会这样？如何解决 请求：

因为您使用的是sort，所以需要为要计算的分数显式设置“” 例如：
{
"size": 1,
"query": {
"bool": {
"must": [
{ "match": {"_all": {"query": "test","operator": "and","fuzziness": "2"}}}
],
"should": [
{ "multi_match" : {
"query": "test"
,"type": "best_fields"
,"fields": ["ObjectData.PRTNAME","ObjectData.EXTERNALID","ObjectData.contactList.VALUE","*SERIES","*NUMBER","ObjectData.INN"]
,"operator": "or"
,"boost": 3
}}
]
}
},
"aggs": {
"byObjectID": {
"terms": {"field": "ObjectID"},
"aggs": {
"latestVer": {
"top_hits": {
"sort": [{"creationDate": { "order": "desc" }}]
,"_source": { "include": ["ObjectData.BRIEFNAME", "creationDate", "ObjectID" ]}
,"size": 1,
'track_scores" : 1
}
}
}
}
}
}
下面的答案无效吗？
