_search 操作响应错误
Cannot search on field [xxxxx] since it is not indexed.
问题原因：
创建索引时，字段类型被设置成不能被索引
解决方案：
1、去掉"index"属性
2、"index"属性值改为true
unknown type for collapse field ‘xxx’, only keywords and numbers are accepted
问题原因：
collapse只允许keywords或者numbers类型，字段xxx不是keywords或者numbers类型
解决方案：
修改对应field的类型为keywords或者numbers类型
