I am pulling a URL from the address bar and parse it down until I get this
(The 'sortby' changes so I have to detect it dynamically)

sortby=industry&tuition=true

OR

sortby=industry

I want this to return

tuition=true

OR

Nothing

This is the regex I am currently using. It works for one but not the other.
/(^sortby=)[A-Za-z|\_|\+|\W]{1,}&/

Thank you for you time!
