Elasticsearch Point In Time Request API in Golang
问题
我正在尝试使用官方的go-elasticsearch库，在golang中使用点在时间（Point in Time）API。我似乎找不到任何解释如何使用它的文档。
我已经能够创建一个OpenPointInTime对象并检索到一个PIT id。我无法弄清楚该如何使用它，或者在elasticsearch.Client.Search函数中放置它的位置。我也没有找到示例。
有人可以给出一个使用官方库的基本示例吗？
英文:
I'm trying to use the point in time api in golang using the official go-elasticsearch library. I can't seem to find any documentation that explains how to use it.
I've been able to create a OpenPointInTime object and retrieve a PIT id. I can't figure out what to do with it or where to place it in the elasticsearch.Client.Search function. I haven't been able to to find an example either.
Can anyone give a basic example using the official library.

在浏览了elasticsearch库的GitHub存储库上的已关闭问题后，我找到了这个问题线程：https://github.com/elastic/go-elasticsearch/issues/234
根据这个线程，我需要从OpenPointInTime响应中获取一个PIT id，并将其添加到请求体中。
以下代码对我有效：
var query_buffer bytes.Buffer
body := `
{
"query": {
"term": {
"_id": "AkUN7YUB2JzVdyKtJ8bD"
}
},
"pit": {
"id": "your pit id here",
"keep_alive": "3m"
}
}
`
es, _ := elasticsearch.NewDefaultClient()
json.NewDecoder(&query_buffer).Decode(&body)
res, err := es.Search(
es.Search.WithAllowPartialSearchResults(true),
es.Search.WithBody(&query_buffer),
)
请注意，这只是一个示例代码片段，具体的实现可能因你的需求而有所不同。

After going through the closed issues on the github repo of the elasticsearch library, I found this issue thread: https://github.com/elastic/go-elasticsearch/issues/234
According to this thread, I need to get a PIT id from OpenPointInTime response and add it to the body.
This worked for me:
var query_buffer bytes.Buffer
body := `
{
"query": {
"term": {
"_id": "AkUN7YUB2JzVdyKtJ8bD"
}
},
"pit": {
"id": "your pit id here",
"keep_alive": "3m"
}
}
`
es, _ := elasticsearch.NewDefaultClient()
json.NewDecoder(&query_buffer).Decode(&body)
res, err := es.Search(
es.Search.WithAllowPartialSearchResults(true),
es.Search.WithBody(&query_buffer),
)
