It uses a combination of punctuation and conjunctions, read left to right, to indicate to a search engine that you want a specific result. What is a Boolean search?Ī Boolean search is a way of looking for specific search results by using a combination of modifiers to organize content. With Boolean searching, you can extend this concept to search engines when selecting the best job candidate based on what requirements you’re looking for. You can use Boolean logic to decide what combination of variables produces a “true result,” or a drink the speaker wants. “I want a cold, non-dairy coffee drink or a hot, caffeinated drink with no sugar but I don’t want green tea” combines multiple conditions. Finally, “I want a drink that is not dairy-based” makes any drink with milk “false” or unacceptable based on the terms.īoolean logic can become infinitely complicated to produce a more specific result. An iced latte would be “true” because it fits both requirements, while a hot coffee would be “false” because it isn’t cold. “I want a cold and caffeinated drink,” indicates a completely different set of acceptable beverages. For example, “I want coffee, tea or a smoothie,” indicates that any of those three variables is an acceptable drink, or a “true” variable, according to Boolean logic. You can apply Boolean logic to math and to real-world scenarios. Boolean logic comes from a mathematician named George Boole, who created a theory that every variable piece of data can be fit into one of two categories: either “true” or “false.” Just like algebra has a set order of operations for solving equations, search engines interpret Boolean searches according to a set of rules known as Boolean logic, allowing for consistent search results. To use Boolean searching effectively, you should first understand the basics of Boolean logic.
