   It may be worth noting that this is the first time anyone said anything 
about how many words are involved, or whether duplicates should be counted 
separately. This just goes to show that when one is optimizing code, it helps to 
have detailed knowledge of the purpose(s) that code is intended to serve.
   So: Counting the duplicates matters, and working with an arbitrary number 
of words matters. Anything else? F'rinstance, would it matter if the code 
keeps track of which line-numbers the target phrases were found in -- "Phrase X 
found 5 times, in lines 1, 2, 5, 67, 68", that sort of thing? Would it matter if 
any of the lines you're searching includes more than one instance of a target 
phrase?
