Good day monks. I am celebrating Labor Day weekend by laboring :-(

I am trying to process some text to consistently tokenize references to people. I am using the following regexp to do this for Condoleeza Rice: 

$text =~ s/(national security adviser )?(dr. |doctor )?(condoleeza )?r
+ice/condoleezarice/ig;

The problem is that this will match the substring "rice" in any old word. I guess I could fix this with anchors or a brute-force enumeration of options. But I'm wondering if there is a more elegant way to rewrite this regexp so the second and third terms function as a non-exclusive or. I other words (whether or not the title is in front of her name) it should match only these cases
  1. dr. rice
  2. doctor rice
  3. dr. condoleeza rice
  4. doctor condoleeza rice
  5. condoleeza rice
I'm having trouble puzzling it out. The following expression 
((dr. |doctor )|(condoleeza ))rice

doesn't match the first word of items 3 or 4 because the alternation operator | is functioning as an exclusive or. Your advice appreciated.

TIA....
