Here's a simple bash script to grep all the perl* perldoc pages. If you're on Windows, as I am at the moment, I recommend Cygwin, as it makes life so much nicer. :) 

#!/bin/bash

PAGER=/bin/cat
for i in `perl -e 'print join " ", map { /^\s+(perl\w+)/ ? $1 : () } \
+`perldoc perl\`'`; do
  echo "$i:"
  perldoc "$i" | grep $*
done
