title: Show text only when link is clicked
body: <p>I have a client which owns an index site. The index includes phone numbers for the companies listed. I want the phone number to not show up in search results and only show up when the user enters the index page and clicks a link. I don't currently use jQuery on the site, but I'm not apposed to adding it, if it makes things easier (I'm guessing it will).
  Any ideas on how to implement this?</p>
