Which search method uses two parallel searches offset by 90°?

The grid search method is characterized by conducting two parallel searches that are offset by 90°. This systematic approach resembles a checkerboard pattern, where searchers move in straight lines across an area in one direction and then return in a perpendicular direction. This method is particularly effective for ensuring thorough coverage, as it allows for overlapping search areas and aids in the discovery of evidence or clues that might otherwise be missed.

In scenarios where maximum coverage is required, such as searching large outdoor areas, the grid search can enhance the likelihood of finding important items or information. The method’s structure helps ensure that even small or hidden objects can be located, reinforcing its value as a reliable search technique in investigations.
