更新商品索引，捕获 ‘非法参数’ 异常？

由于之前创建商品索引是‘type’类型写错了，写成了：

curl -H 'Content-type:application/json' -XPOST http://localhost:9200/products/_mapping/_doc?pretty -d '{
    "properties": {
        "type": {"type": "text", "analyzer": "ik_smart"},

导致现在更新索引是抛出异常：

{
  "error" : {
    "root_cause" : [
      {
        "type" : "illegal_argument_exception",
        "reason" : "mapper [type] of different type, current_type [text], merged_type [keyword]"
      }
    ],
    "type" : "illegal_argument_exception",
    "reason" : "mapper [type] of different type, current_type [text], merged_type [keyword]"
  },
  "status" : 400
}

这个要怎么解决啊？
