Which term describes a search method in which the area is divided into lanes and searched by one or more people in both directions until the entire area has been examined?

• A. Grid search
• B. Sweep search
• C. Zone search
• D. Strip/line search pattern

Answer: (D)

Dividing the area into parallel lanes and searching each lane in a back-and-forth sweep is a strip/line search pattern. The strength of this approach lies in providing thorough, systematic coverage with clear, manageable sections. By assigning searchers to consecutive lanes and having them work in both directions, you minimize gaps and keep their progress easy to track. This method is especially effective for open or long, narrow spaces like fields, corridors, or rectangular zones where continuous, orderly coverage is possible.

Compared with other methods, this pattern prioritizes steady, line-by-line coverage rather than crossing the area in two directions or breaking the space into larger zones. That makes it faster to deploy and easier to coordinate when you have multiple people, while still ensuring every part of the area is examined.
