Boolean Searching or How to choose your slice of pizza at the Pizza Buffet .
Vinny Diagrams Pizza Buffet Toppings: Pepperoni   Sausage  Garlic Onion Anchovies Crawfish  (Vinny is from New Orleans)
Boolean Operators AND OR NOT
Vinny Buffet is also known for his odd figure eight shaped pizzas, because he is little careless when placing the pizzas into the oven.  So, that makes finding the right slice an additional challenge.
 AND By using  AND  we are requiring both of the search terms (in this case  pizza toppings) to appear somewhere in the document (make that pizza). In Vinnys merged pizzas, it is only the middle slice we want. The one with both  Pepperoni and Sausage!
 OR By using  OR  we are saying either of the toppings can appear somewhere on the pizza. In Vinnys merged pizzas any slice is okay!
 NOT  NOT  excludes those search terms (like anchovies) that follow it. In Vinnys merged pizzas we dont want any slice of pizza that has anchovies!  Just the Crawfish side please!
Lets try Searching for articles using these Boolean operators. AND
