## FAQ
|
|
|
|
### Why doesn't the text composition system work well with onSearch in controlled mode?
|
|
|
|
Please use `onChange` to manage control state. `onSearch` is used for searching input which is not same as `onChange`. Besides, clicking on the option will not trigger the `onSearch` event.

### Part of api from v3 not available in v4?
|
|
|
|
AutoComplete is a Input component support auto complete tips which should not support `labelInValue` prop to modify dispaly value in input. In v3, AutoComplete realization can not handle case that user type match of both `value` & `label` are the same. v4 not longer support `label` as the value input.
