elasticsearch2.4.4多行删除

今天忽然需要删除某个索引下面的某个type下面的所有xxxx字段以lrz开头的数据，查看elasticsearch2.4.4文档，发现只有根据id一个一个删除，类似如下写法：

$ curl -XDELETE ‘http://localhost:9200/twitter/tweet/1’

查看文档，没有满足该类需求的方法，偶然看见文档如下：

Delete By Query Pluginedit
The delete-by-query plugin adds support for deleting all of the documents (from one or more indices) which match the specified query. It is a replacement for the problematic delete-by-queryfunctionality which has been removed from Elasticsearch core.

Internally, it uses Scroll and Bulk APIs to delete documents in an efficient and safe manner. It is slower than the old delete-by-query functionality, but fixes the problems with the previous implementation.
