![]() Boolean Search Recruitingįor these reasons, Boolean search is incredibly popular in the hiring search. It weeds out irrelevant information and focuses on results that have been preliminarily vetted by the search engine itself. A Boolean search saves you time by adding specificity and context to your research. For example, if you want to learn more about the foreign policy of Thomas Jefferson’s presidency, you would type in quotes specific words such as “Thomas Jefferson’s presidency foreign policy.” This filters out information about Jefferson writing the Declaration of Independence, founding the University of Virginia, or building Monticello. The Boolean Search simply takes the cafe example and extends its principles to any internet search. 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. To effectively conduct a Boolean search, it helps to first understand Boolean logic. You're essentially telling the search engine that you want all of these words, in this specific order, or this specific phrase.Are you a job seeker? Find jobs. The Boolean search operator NEAR is equal to putting a search query in quotes, i.e., "sponge bob squarepants".The Boolean search operator OR is the default setting of any search engine meaning, all search engines will return all the words you type in, automatically.The Boolean search operator NOT is equal to the "-" symbol.The Boolean search operator AND is equal to the "+" symbol.The most common strategy is to use the standard Boolean operators AND, OR, NOT, or NEAR. Where does the term Boolean originate? George Boole, an English mathematician in the 19th century, developed "Boolean Logic" in order to combine certain concepts and exclude certain concepts when searching databases. ![]() Most Internet search engines and Web directories default to these Boolean search parameters anyway, but a good Web searcher should know how to use basic Boolean operators. Boolean searches allow you to combine words and phrases using the words AND, OR, NOT and NEAR (otherwise known as Boolean operators) to limit, widen, or define your search.
