让我们假设您有一个类似于["36088175", "36088176"]的数组中的ID。
查询将是：
{
"query": {
"terms": {
"_id": ["36088175", "36088176"]
}
}
}
有关更多细节，请查看术语查询 - https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-terms-query.html
英文:
let's say you have ids in array like ["36088175", "36088176"]
The query will be
{
"query" : {
"terms" : {
"_id" : ["36088175", "36088176"]
}
}
}
see terms query for more details - https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-terms-query.html

{
"_id" : "fIjOTW8BkTKnAOE5HVit"
},
{
"_id" : "fojOTW8BkTKnAOE5UliD"
}
]
}
