Email to ticket expressions

I was creating a prompt in incident IQ to where if someone emails a specific email address it'll create a ticket based on what's in the subject/body of the email says when I type in the value %wifi%  and then send an email to that address the ticket is created with no issues, but when I use the value
%(network|wifi|internet)% and send a email with all other rules being the same the ticket isnt being created. Using the value tester it says all expressions are passed successfully as long as I include any of the words network, wifi, or internet. Am I structuring the values wrong?
