因为es需要满足多个组的数据存储，所以字段类型没法确定，就用keyword和text作为通用类型保存所有数据，但是需要对某些字段排序，这些字段一般是数值，需要怎么做？
排序实例：
/index/type/_search?pretty
{
"from": 0,
"size": 20,
"query": {"match_all":{} },
"sort": {
"re_5": {
"order": "desc"
}
}
}
排序字段re_5是数值，例子："1233"，困扰是使用这个查询语句返回的不是按照re_5的数值降序排列的。

测试信息：

1、{

以上是创建的测试数据，
请求参数：
{
"from": 0,
"size": 20,
"query": {"match_all":{} },
"sort": {
"re_1": {
"order": "asc"
}}}
返回的顺序是乱的？并不是按照re_1的数值排序。我哪里出错了吗？求指点。

mapping：

{
"from": 0,
"size": 20,
"query": {"match_all":{} },
"sort": {
"name": {
"order": "asc"

返回依然是乱序的，猜测应该是对keyword类型的排序应该是不行的，最后想到的解决办法就是用script的方式将字段转换成number类型进行排序了，如果有好的办法的希望能不吝赐教，谢谢！

使用脚本批量修改费时费力、而且很容易造成 ES 挂掉。
