I need a pure regex solution, as it will be used with findAndReplaceDomText which
searches for regular expression matches in a given DOM node and replaces or wraps each match with a node or piece of text that you can specify.
If I have a string that has the word "red" occur n times in it. I want to be able to find the nth occurrence in the string.
Find "red" at 3rd occurrence should find bolded string:
For example
Alfred the Red Baron, loved autumn for its red auburn colors. But Alfred was sad as he no longer had red to paint the red auburn colors.
