ES mapping可以修改include_in_all，也可以修改index_options，norm，但是无法修改_all属性！

               }
            }
        }
}'   

可以看到，是可以直接修改include_in_all和index_options、norms属性的！

注意是没有办法修改_all属性的！
curl -XPOST "http://localhost:9200/productindex/product/_mapping?pretty" -d '{
     "product": {
                "_source": {
                    "enabled": false
                },
                "_all": {
                    "enabled": false
                }
        }
}'   

会提示：
MergeMappingException: Merge failed with failures {[mapper [_all] enabled is false now encountering true]}
