Select - When Inline filter field is open, allow us to also specify a valid pattern that can be searched

Is this a new component or an extension of an existing one?
Select

Describe the feature
When an inline filter is open user can type any characters. even though we might know the selections are only using digits, etc.
If this happens, the component just says:
noResultsFoundText: 'No results found',
Ideally it would say the entered text contains letters when it should just contain numbers, etc

Are there visuals for this feature? If applicable, please include examples for each state and for varying widths
maybe this?

Any other information?

该 issue 没有指出文件、入口点或测试。首先定位 Select inline-filter 的实现及现有的过滤测试，然后明确如何提供有效模式，以及对于无效输入预期的消息和行为；当约定的行为已实现并由测试覆盖时，即视为完成。
