1) The document discusses using Boolean operators such as AND, OR, and NOT to search for specific pizza toppings at Vinny Diagram's Pizza Buffet where the pizzas are oddly shaped and sometimes merged together. 2) AND requires both search terms to be present, OR allows either term, and NOT excludes the term after it. 3) For example, using AND would find a middle slice with pepperoni and sausage, OR would accept any slice, and NOT would avoid slices with anchovies.
Boolean Searching (SDCC)
- 1. Boolean Searching or How to choose your slice of pizza at the Pizza Buffet .
- 2. Vinny Diagram’s Pizza Buffet Toppings: Pepperoni Sausage Garlic Onion Anchovies Crawfish (Vinny is from New Orleans)
- 3. Boolean Operators AND OR NOT
- 4. 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.
- 5. “ 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 Vinny’s merged pizzas, it is only the middle slice we want. The one with both Pepperoni and Sausage!
- 6. “ OR” By using “ OR ” we are saying either of the toppings can appear somewhere on the pizza. In Vinny’s merged pizzas any slice is okay!
- 7. “ NOT” “ NOT” excludes those search terms (like anchovies) that follow it. In Vinny’s merged pizzas we don’t want any slice of pizza that has anchovies! Just the Crawfish side please!
- 8. Let’s try Searching for articles using these Boolean operators. “AND”
- 9. “OR”
- 10. “NOT”
