elasticSearch通配符*

发布时间：2021-08-23 15:51:03编辑：雪饮阅读（）

ElasticSearch关于_all是用来匹配所有的索引的，这个是上篇中学习的内容。那么对于通配符在elasticSearch的应用，就拿*来说，他可以匹配例如以某个前缀的的索引，例如下面这个请求

http://localhost:9200/school*/_search post

这里相当于匹配了所有school为前缀的索引，那么像是前面我们的schools和schools2以及schools_gov这些索引也都是可以匹配到的。

那么请求体假比是：

{

   "query":{

      "query_string":{

         "query":"CBSE"

      }

   }

}

则这里是在上面匹配的结果中在检索下CBSE单词。

那么一个响应结果如：

{

    "took": 3,

    "timed_out": false,

    "_shards": {

        "total": 3,

        "successful": 3,

        "skipped": 0,
