![]() ![]() That’s helpful for the cafe, but how does this extend to the internet? What Is a Boolean Search? All conditions must be met for a “true” result. If one of these variables is false, say, the barista uses dairy milk, I don’t want the drink and won’t pay for it. You see it daily at your favorite cafe: “I’d like an iced, dairy-free latte with a double shot of espresso.” The combination of these variables “iced” AND “dairy-free” AND “latte” AND “double shot of espresso” produces the true result. I may be curious about the tavern, but I will go somewhere else for a cold, caffeinated beverage.īoolean logic can become infinitely more complicated to produce a specific result. But if even one of these is false (the tavern doesn’t sell caffeinated drinks OR they don’t have cold drinks because their ice machine is broken) then the total output is false. “Caffeine” becomes a second variable in this equation: “IF (cold drink) AND (caffeine), then I will buy a drink at the tavern.” If both of these are true, then the output is true, meaning I will go to the tavern and buy a drink. Now, because I am tired, the drink must also contain caffeine. Here, “cold drink” can be the first variable in an equation: “If I can purchase a cold drink, then I will go to the tavern.” As long as the tavern sells drinks that are not hot, you have a variety of drink options to choose from. Here’s an everyday example: I want a cold drink. He believed that every piece of variable data could be fit into one of two categories: “true” or “false”, with nothing in the middle. Boole did this by putting formal logic into mathematical form. A 19th century English mathematician and logician, Boole initially intended to provide a foundation for and extend the applicability of Aristotelian logic. While it may sound exotic or mythical, Boolean logic was simply named after the man who developed it, George Boole. This is our third book, following “300 Best Boolean Strings” (now in its 4th edition) and “Sourcing Hacks” (2nd edition).To effectively conduct a Boolean search, it helps to first understand Boolean logic. If you decide that you are ready to get certified, the next Exam week is January 25-31, 2020. Our test-takers have reported feeling accomplished, having improved their skills and understanding of Sourcing – and having fun taking the exams! We hope you enjoy the questions as well. Each question should take you between one and six minutes to answer. There is no need for paid subscriptions to any sites. The questions in the book are just like those we give at our exams. The eBook offers “learning by doing” as well as “learning by example.” You would be experiencing optimal approaches to a task, the right way of thinking, and proper tool selections. This book can serve as an aid in assessments.īy trying to solve the sample questions and comparing your solutions with the ones provided, you will improve your sourcing skills, knowledge, and confidence. Reviewing solutions and correct answers to the concrete challenges are always educational, as well. Assessments can improve Recruiting performance by identifying Sourcing skill gaps and taking action to fix them. In our industry, assessment of Sourcing skills is vital due to the apparent lack of adequate performance measurements for a Sourcer. However, the book can also serve to help to assess your and your team’s Sourcing skills (whether your goal is to get certified or not) – or perhaps choose questions from the book to use at interviews when hiring Recruiters. We had initially conceived the book as an aid to prepare for our Sourcing Certification Exams. ![]() I am happy to announce a new eBook, “Sourcing Answers,” that David Galley and I have just e-published. ![]()
