For example, if you wanted to find resumes where the candidate had healthcare experience, you could search “hospital OR clinic” to pull up resumes of anyone who worked at a hospital or medical clinic.īoolean searching exists to give people more relevant results to whatever they are searching for. It uses a combination of punctuation and conjunctions, read left to right, to indicate to a search engine that you want a specific result. 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.Ī Boolean search is a way of looking for specific search results by using a combination of modifiers to organize content. 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.
