Find In Path Isn't Returning Known Function mail( [Solved]

When using Find In Path for the specific term mail( or other functions no result are found.  Even if I search the whole project.  Other terms are working to find strings in that same file.  I've done invalidate cache / restart and still not results.

Edit: Ok so as I was typing this I noticed Regex option was checked.  Parenthesis would be considered a special regex character.  Gonna post anyway, maybe help someone out.
