也可以使用如下DSL

[root@esdbqp bin]# curl -XDELETE "http://localhost:9200/filebeat-2016.01.28/log/_query?pretty=true" -d '
{
 "query": {
   "term": {
      "tags": "multiline"
    }
  }
}'
{
  "took" : 0,
  "timed_out" : false,
  "_indices" : {
    "_all" : {
      "found" : 0,
      "deleted" : 0,
      "missing" : 0,
      "failed" : 0
    }
  },
  "failures" : [ ]
}
[root@esdbqp bin]#

我觉得CLI下面这种方法比较麻烦

Tip:

不加 pretty=true 输出仍然为jason，但因为没有换行，显示会很凌乱
事实上这个插件也还是使用的 scroll 加 bulk 的方式在内部进行实现的

Internally, the query is used to execute an initial scroll request. As hits are pulled from the scroll API, they are passed to the Bulk API for deletion.

执行结果显示正常删除了110条记录

进行查看，剩下4104条，而原来总共4214条，确实是删掉了这么多

[root@esdbqp bin]# curl "http://localhost:9200/filebeat-*/log/_search?pretty=true&q=tags:multiline" | head -n 20
