清理elasticsearch的索引

直接到 elasticsearch data文件夹里删掉就行了，但怎么也得做的有点技术含量不是？
上网站看了看文档，其实也挺简单一条命令就行了
# curl -XDELETE '*' 清理掉了所有 3月份的索引文件，我发现curl 删除比rm删除要快出很多 


#curl -XDELETE '9200/*2016.*'
#
#curl -XDELETE '9200/*2017.01.*'
#
#curl -XDELETE '9200/*2017.02.*'
#
#curl -XDELETE '9200/*2017.03.*'
#
#curl -XDELETE '9200/ctivityescort-2016.*'   
#
#curl -XDELETE '9200/ctivityescort-2017.02.*'
#
#curl -XDELETE '9200/ctivityescort-2017.03.*'
#
#curl -XDELETE '9200/ctivityserver-2017.03.*'
