如何删除某个索引下的所有数据？
$ curl -X POST "localhost:9200/${index}/${tpye}/_delete_by_query?pretty" \
-H 'Content-Type:application/json' \
-d '{
"query": {
"match_all":{}
}
}'
删除所有数据：（注意请求方式是Post，只删除数据，不删除表结构）
$ curl -X POST "xx.xx.xx.xx:9200/${index}/_delete_by_query?pretty" \
-H 'Content-Type:application/json' \
-d '{
"query": {
"match_all":{}
}
}'
