c# - Elasticsearch索引文档，但下一个查询返回0个匹配

Question

遵循要求后

POST http://192.168.36.235:9200/object_folder666_integration_debug/_doc?pretty=true&error_trace=true HTTP/1.1
Accept: application/json

Host: 192.168.36.235:9200
Content-Length: 1325

{/* -object content- */}

我收到了201条回复，看来文档已被索引。

HTTP/1.1 201 Created

content-type: application/json; charset=UTF-8

{
  "_index" : "object_folder666_integration_debug",
  "_type" : "_doc",
  "_id" : "d99jLXUBNoTXVKywvedm",
  "_version" : 1,
  "result" : "created",
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "failed" : 0
  },
  "_seq_no" : 0,
  "_primary_term" : 1
}

但是，当我执行第二次查询(搜索)时，我的命中率为0，不知道出了什么问题。

问题在于索引的刷新间隔设置为-1，这意味着除非您手动执行，否则永远不会进行自动刷新。
因此，您有两种选择:
答:保持这种方式，但是在每次建立索引之后，都需要运行此命令以刷新索引

GET http://192.168.36.235:9200/_refresh

B.您决定更改此设置，并通过仅运行一次索引来更定期地刷新索引(默认值为每秒)

PUT GET http://192.168.36.235:9200/object_folder666_integration_debug/_settings
{
  "index.refresh_interval": "1s"
}
