How do you determine whether the user is entering a regex? All plain strings are valid regexes.
I would think the best approach is to offer a checkbox to switch between plain text and regex search. Then the user won't be confused why "hello." matches "hellos", or why search-as-you-type just stopped working in the middle of a string just because they typed some punctuation. In that case, you can just change the sendsWholeSearchString property depending on the search mode.
If you're dead-set on not offering a toggle, you could always ignore regex searches in the action method and implement -control:textView:doCommandBySelector: to process regexes when the field editor gets insertNewline:.
