title: In OpenGrok how do you do a full search for special non-alphanumeric characters
body: <p>I am trying to search my codebase for code that calls a function named "foo" so I am searching for "foo(" but the results I'm getting includes everything with the word foo in it which includes css, comments and strings that don't even have the trailing open parenthesis.</p>
  
  <p>Anyone know how to do a search for strings that include special characters like <code>),"'</code>?</p>
