[R] matching strings in a list

Say I have a list: [[1]] "I like google" [[2]] "Hi Google google" [[3]] "what's up" and they are tweets. And I want to find out how many tweets mention google (the answer should be 2). If I string split and unlist them, then I would get the answer of 3. How do I make sure I get just 2? --
