"_id" 上的简单 term query 对我有用。
所以我创建了一个简单的索引并分别添加了两个文档,用于两种不同的类型:
PUT /test_index
POST /test_index/_bulk
{"index":{"_type":"type1","_id":1}}
{"name":"type1 doc1"}
{"index":{"_type":"type1","_id":2}}
{"name":"type1 doc2"}
{"index":{"_type":"type2","_id":1}}
{"name":"type2 doc1"}
{"index":{"_type":"type2","_id":2}}
{"name":"type2 doc2"}
这个查询将返回两个 id 为 1 的文档:
POST /test_index/_search
{
"query": {
"constant_score": {
"filter": {
"term": {
"_id": "1"
}
}
}
}
}
...
{
"took": 5,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 2,
"max_score": 1,
"hits": [
{
"_index": "test_index",
"_type": "type1",
"_id": "1",
"_score": 1,
"_source": {
"name": "type1 doc1"
}
},
{
"_index": "test_index",
"_type": "type2",
"_id": "1",
"_score": 1,
"_source": {
"name": "type2 doc1"
}
}
]
}
}
这是我使用的代码:
