Search is a  ubiquitous property of life. Although diverse domains have worked on search  problems largely in isolation, recent trends across disciplines indicate that  the formal properties of these problems share similar structures and, often,  similar solutions. Moreover, internal search (e.g., memory search) shows  similar characteristics to external search (e.g., spatial foraging),  including shared neural mechanisms consistent with a common evolutionary  origin across species. Search problems and their solutions also scale from  individuals to societies, underlying and constraining problem solving,  memory, information search, and scientific and cultural innovation. In  summary, search represents a core feature of cognition, with a vast influence  on its evolution and processes across contexts and requiring input from  multiple domains to understand its implications and scope.
