Subject: Regexp to esclude substrings

I'm trying to resolve a very simple problem, but I'm encountering some 
issues.

Input: "this is a string where you can find some words"
Output: [this, string, where, can, find, some, words]

So I'm trying to eliminate ' is ', ' a ' and ' you ' from the string 
(note the spaces, 'this' shouldn't be eliminated just because it 
includes 'is').

I tried the following (and many others), but it doens't work:
my_string = input_string.gsub!(/\s+(is|a|you)\s+/i,' ').split

Any hints?
