我下面的文档具有弹性，并且仅需要从聊天数组中获取sessionId：3dddf4ab的对话，但是我正在获取整个文档
Elastic文档：
{
"_index" : "myindex",
"_type" : "_doc",
"_id" : "1",
"_version" : 1,
"_seq_no" : 0,
"_primary_term" : 1,
"found" : true,
"_source" : {
"chatid" : "1",
"conversations" : [
{
"conversation" : {
"conversationId" : "3dddf4ab",
"startTime" : 1573555131306,
"question" : "abc",
"language" : "English",
"type" : "123",
"answer" : "weeqwew",
"feedback" : {
"rating" : 1,
"endTime" : 0,
"votes" : 1,
"likes" : 1
}
}
},
{
"conversation" : {
"conversationId" : "29363306",
"startTime" : 1567756384492,
"question" : "wer",
"language" : "English",
"type" : "456",
"answer" : "zxsz",
"feedback" : {
"rating" : 0,
"endTime" : 0,
"votes" : 0,
"likes" : 0
}
}
},
{
"conversation" : {
"conversationId" : "3dddf4ab",
"startTime" : 1573555131308,
"question" : "qwer",
"language" : "English",
"type" : "789",
"answer" : "hjhlh",
"feedback" : {
"rating" : 0,
"endTime" : 0,
"votes" : 0,
"likes" : 0
}
}
},
{
"conversation" : {
"conversationId" : "29363306",
"startTime" : 1567756384499,
"question" : "klklkl",
"language" : "English",
"type" : "674",
"answer" : "kjjj;",
"feedback" : {
"rating" : 2,
"endTime" : 0,
"votes" : 4,
"likes" : 4
}
}
}
]
}
}
在Kibana中搜索查询DSL：
{
"query": {
"match": {
"chat.conversation.conversationId": {
"query": "3dddf4ab",
"type": "phrase"
}
}
}
}
预计如下，但获取整个文档：
这是我期望的输出，相反，我正在获取包括其他对话ID在内的整个文档

Suven，您需要从嵌套查询中检索内部匹配，如下所示：
POST testindex/_search
{
"_source" : false,
"query": {
"nested": {
"path": "conversations",
"query": {
"term": {
"conversations.conversation.conversationId": {
"value": "3dddf4ab"
}
}
}
, "inner_hits": {
}
}
}
}
响应：
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 0.6931472,
"hits": [
{
