Searching Techniques and Strategies Tutorial

Boolean Searching - AND, Cont.

This is sometimes difficult to conceptualize, so here's a visual representation of what an AND search would look like. Think of circle "A" as representing all the records that contain the word "dog", and circle "B" as representing all the records that contain the word "cat."

circle A
circle B


The purple space where they intersect represents all the records that would be returned by the search dog and cat.
