Boolean Searching - NOT, Cont.

Here are visual representations of NOT searches. Notice that it does make a difference which order your search terms are placed. "Dog not cat" returns very different results than "cat not dog."

The purple spaces represent all the records that would be returned by the search "dog not cat," and "cat not dog."
