elasticsearch 弹性搜索路由突然失效

我的弹性6.8和路由似乎不工作。我举的例子

PUT my_index/_doc/2?routing="user1" 
{
  "title": "This is a document"
}

{
  "_index" : "my_index",
  "_type" : "_doc",
  "_id" : "2",
  "_version" : 2,
  "result" : "updated",
  "_shards" : {
    "total" : 2,
    "successful" : 1,
    "failed" : 0
  },
  "_seq_no" : 1,
  "_primary_term" : 1
}

在应用

GET

query时

GET my_index/_doc/2?routing="user1"

没有结果。看起来很奇怪，我是不是遗漏了什么

{
  "_index" : "my_index",
  "_type" : "_doc",
  "_id" : "2",
  "found" : false
}

更新#1

以下API导致错误（取自文档）

---

由于在

PUT my_index/\u doc/1？routing=user1&refresh=true

中的

refresh=true

末尾添加了1或2个空格字符，因此出现以下错误

 {
    "type": "illegal_argument_exception",
    "reason": "Unknown value for refresh: [true ]."
  }

来自elasticsearch源代码：

if ("".equals(value)) {
                // Empty string is IMMEDIATE because that makes "POST /test/test/1?refresh" perform
                // a refresh which reads well and is what folks are used to.
                return IMMEDIATE;
            }
            throw new IllegalArgumentException("Unknown value for refresh: [" + value + "].");

删除结尾的空白，然后再次尝试为文档编制索引

添加一个工作示例：

索引数据：

PUT http://localhost:9200/{{index-name}}/_doc/1?routing=user1&refresh=true

{
    "name":"multi grain bread"
}

作为回应，你会得到

{
  "_index": "64762507",
  "_type": "_doc",
  "_id": "1",
  "_version": 1,
  "result": "created",
  "forced_refresh": true,
  "_shards": {
    "total": 2,
    "successful": 1,
    "failed": 0
  },
  "_seq_no": 0,
  "_primary_term": 1
}

使用检索文档时

GEThttp://localhost:9200/{{index name}}/_doc/1？routing=user1

作为回应，您将获得：

{
  "_index": "64762507",
  "_type": "_doc",
  "_id": "1",
  "_version": 1,
  "_seq_no": 0,
  "_primary_term": 1,
  "_routing": "user1",
  "found": true,
  "_source": {
    "name": "multi grain bread"
  }
}

在传递路由字段时，刷新是否为强制属性？p请检查是否通过路由字段而不通过refresh@Nag

refresh

在传递路由字段时不是强制属性。甚至您也不应该在每个索引操作中添加

？refresh=true

，因为它会降低索引速度。@Nag

refresh

的添加是为了在操作发生后立即刷新相关的主碎片和副本碎片（而不是整个索引），以便更新后的文档立即出现在搜索结果中。请浏览此文档以了解有关

？刷新
@Nag的更多信息如果有助于您解决问题，请不要忘记投票并接受我的答案：）这是真的，但我想知道为什么查询没有返回结果（来自我最初发布的问题）
