ElasticSearch for Long 类型 (ES 5.0.4) 上的嵌套查询

Question

这是我关于堆栈溢出的第一个问题，请原谅我的错误。我将来会改进它们。 我也是弹性搜索的新手。好的，所以我正在尝试在弹性搜索 (5.0.4( 中进行完全匹配。请求不是执行完全匹配，而是返回存在的所有文档。 不确定此行为。

这是映射

{
"properties":{
"debug_urls":{
"properties":{
"characteristics":{
"type":"text",
"fields":{
"keyword":{
"type":"keyword",
"ignore_above":256
}
}
},
"url_id":{
"type":"long"
}
},
"type":"nested"
},
"scanId":{
"type":"text",
"fields":{
"keyword":{
"type":"keyword",
"ignore_above":256
}
}
}
}
}

这是我的要求。

{
"query": {
"nested": {
"path": "debug_urls",
"query": {
"match": {
"debug_urls.url_id": 1
}
}
}
}
}

收到的答复，

"total":5,
"successful":5,

},
"hits":{
"total":1,

}
}

}
}

如果您只想查看与条件匹配的嵌套文档，则可以利用嵌套inner_hits：

{
"_source":["scan_id"],                     <--- add this line
"query": {
"nested": {
"path": "debug_urls",
"query": {
"match": {
"debug_urls.url_id": 1
}
},
"inner_hits": {}                    <--- add this line
}
}
}
