elasticsearch elasticsearch查找数组中给定数字项具有相同属性值的文档
首先，我想展示一下文档的简化结构
{
"_id": "413123123",
"_source": {
"description": {
"firstLine": "this is my description",
"secondLine": "some value"
},
"InsertDetails": {
"Timestamp": "2020-06-12T11:14:36+0000"
},
"Links": [
{
"LinkDetails": {
"linkId": 2342,
"type": "Link",
"dateCreation": "2012-09-21T08:42:09+0000",
"typeId": 404019,
"typeOfLink": "http"
}
},
{
"LinkDetails": {
"linkId": 321313,
"type": "Link",
"dateCreation": "2012-08-21T08:42:09+0000",
"typeId": 404019,
"typeOfLink": "http"
}
},
{
"LinkDetails": {
"linkId": 1231,
"type": "Link",
"dateCreation": "2012-09-21T08:42:09+0000",
"typeId": 32323,
"typeOfLink": "https"
}
},
{
"LinkDetails": {
"linkId": 53434,
"type": "Link",
"dateCreation": "2012-11-21T08:42:09+0000",
"typeId": 123231,
"typeOfLink": "wss"
}
}
]
}
}
- 链接数组中的两个项的typeOfLink等于http
- 描述字符串包含单词“this”
- 找到的项目将按日期描述排序
{
"query": {
"bool": {
"must": [
{
"bool": {
"must": [
{
"match": {
"Links.LinkDetails.typeOfLink": "http"
}
}
],
"minimum_should_match": 2
}
},
{
"match": {
"description.firstLine": "this"
}
}
]
}
},
"sort": [
{
"InsertDetails.Timestamp": {
"order": "desc"
}
}
]
}
{
"my_index": {
"mappings": {
"en": {
"properties": {
"InsertDetails": {
"properties": {
"Timestamp": {
"type": "date",
"format": "strict_date_optional_time||epoch_millis"
}
}
},
"description": {
"properties": {
"firstLine": {
"type": "string"
},
"secondLine": {
"type": "string"
}
}
},
"Links": {
"properties": {
"LinkDetails": {
"properties": {
"linkId": {
"type": "long"
},
"type": {
"type": "string"
},
"dateCreation": {
"type": "date",
"format": "strict_date_optional_time||epoch_millis"
},
"typeOfLink": {
"type": "string"
},
"typeId": {
"type": "long"
}
}
}
}
}
}
}
}
}
}
首先，您希望对嵌套字段进行筛选。（对象数组） 要获得一致的结果，必须将此字段映射为嵌套字段。 然后，您将不得不使用聚合。 您想要的是只聚合类型为\u的\u链接的“http”值，如果聚合返回的结果超过2个，则返回结果 您的查询将稍微复杂一些：
{
"size": 0,
"query": {
"bool": {
"filter": [
{
"nested": {
"path": "Links",
"query": {
"match": {
"Links.LinkDetails.typeOfLink": "http"
}
}
}
},
{
"match": {
"description.firstLine": "this"
}
}
]
}
},
"aggs": {
"links": {
"nested": {
"path": "Links"
},
"aggs": {
"http_only": {
"filter": {

}
},
"aggs": {
"several_http": {

"min_doc_count": 2
}
,
"aggs": {
"complete_match": {
"top_hits": {
"size": 100
}
}
}
}
}
}
}
}
},
"sort": [
{
"InsertDetails.Timestamp": {
"order": "desc"
}
}
]
}

}
}
},
{

"_type" : "_doc",

"type" : "Link",
"dateCreation" : "2012-08-21T08:42:09+0000",
"typeId" : 404019,

}
}
}
]
}
}
}

}
}
}
}
通过使用给定的聚合，您应该能够执行您想要的操作。您可以共享您的ES索引映射吗？添加了索引映射
