add props maxlength for search input

[smerchkz]

tried to control the maximum amount of text in the search through regex, but it seems not possible. Therefore, I propose a separate prop, so that it is convenient to control the maximum length of the search string

I support this idea!

• Ability to add regex mask to the input field

@adamberecz any update on this prop or any workaround for now?
