3 What is Boolean Searching? Boolean Searching is way to narrow your topic so that you can find good information quickly.

4 Why is it Called “Boolean”? Boolean Searching was named for George Boole, an English mathematician. Mr. Boole was the first to create a binary system of analysis using 1’s and 0’s, the same principle used for comupter language. Mr. Boole was truly ahead of his time.

5 How Does Boolean Searching Work? Boolean searching uses key words for your topic along with the words: AND OR NOT

6 Why??? The computer only looks for what you tell it to look for. Using AND, OR, and NOT tells the computer to include some words or to exclude some words when you are searching for a topic.

7 AND Using AND tells the computer to find information about all the words you typed when they appear together:

8 OR Using OR tells the computer that you want information about either word you typed.

9 NOT Using NOT tells the computer that you want information about one word but NOT another.

10 Let’s See How It Works… You want to know about tigers and their eating habits, so you type in: tigers AND eating This tells the computer that you want everything on the internet that talks about tigers and eating only when they arementioned together. AND

11 You might want sites that mention either tigers or their eating habits, so you type in: tigers OR eating This tells the computer that you want everything on the Internet that talks about tigers or eating. OR

12 You probably got a lot of information. In fact, by now, you have probably gotten some hits about the Tigers football team. This time tell the computer: tigers AND food NOT football This tells the computer that you want everything about tigers and their eating habits, but you do not want anything about football. ANDNOT

13 Conclusion Using Boolean searching narrows your topic. Using AND, OR, or NOT tells the computer exactly what you want. Boolean searching helps you get good information without wasting time. Boolean searching is easy!
