What is primary and secondary sweep?

Primary and secondary sweeps refer to methods used in various contexts, such as search and rescue operations or data collection. A primary sweep involves an initial, thorough search of an area to locate individuals or gather essential information. In contrast, a secondary sweep is a follow-up search that focuses on more detailed or specific aspects, often to ensure nothing has been overlooked in the primary sweep. These concepts can also be applied in fields like emergency response and data analysis, where thoroughness and attention to detail are crucial.
