Boolean searching allows you to combine search terms using AND, OR, and AND NOT operators to narrow or broaden your results. The technique is named after mathematician George Boole and requires all terms to be present for AND, only one for OR, and the second term to be excluded for AND NOT. The document instructs the recipient to look up Boolean searching in a middle school database, email the link, and describe what was found about Boolean operators. It also provides the date of an upcoming battle and reminds students to be quiet in the library.
