Boolean logic will always captivate me. The art of manipulating a search to retrieve search results will never get old. Our use of Boolean commands has certainly changed over the years. We may not be spending hours each day refining our search and combing through thousands of results. Boolean cheat sheets might seem archaic. Memorizing search strings have been replaced by SourceHub, RecruitEm and Hiretual. This isn’t to say that “Boolean” is inevitably dying. As Glen Cathey has repeatedly stated, “George Boole is dead, not Boolean.” Learning and using Boolean commands to search is one of the fundamental concepts of a great sourcer. Each day, other curious sourcers from around the world ask for help building search strings. The creativity and the uniqueness behind each search is fascinating. Take a look at the favorite search strings from some of the top women in sourcing. Use the comments to share your favorite strings.
