Just typing Batteries Not Included without quotes around it is a problem right off the bat because the word "not" is removed from the search as "too common" of a word. So the results that you see are based on the following:
List all threads/post that contain the words "batteries" and "included", then list all threads/posts that contain either the word "batteries" or the word "included".
Using quotes around the phrase gives you everything that you are looking for.
