bucket使用简单查询我得到一堆文档，其中每个文档都有一个{

id。我正在尝试使用sampler聚合来获取它们在一般查询中出现的序列中的桶ID。
但是当我运行上面的查询时，我会按升序获取存储桶，它们甚至不是我从常规查询中得到的存储桶。
E.g。
[22570, 12239]你可以看到聚合不是所需要的。如何按顺序获取{{1}}？
答案 0 :(得分：0)
instance (HasServer a, HasServer b) => HasServer (a :<|> b) where
-- ...
route Proxy (a :<|> b) request respond =
route pa a request $ \mResponse ->
if isMismatch mResponse
then route pb b request $ \mResponse' -> respond (mResponse <> mResponse')
else respond mResponse
ID "sampler": {
"field": "cluster",
"shard_size": 1 // <-- It could be the potential culprit
},
可能都属于同一个分片。由于您已将分片大小指定为1，因此聚合可能只有一个来自分片的聚合，因为聚合中省略了22570, 12239。
