In this video a recursive algorithm is introduced to search through lists efficiently. Searching involves checking for a specific property or value in a list, and can be stopped early if the desired result is found. The implementation of the algorithm involves a bottom-up approach with a single parameter to avoid unnecessary list chopping. The base case involves returning minus one if the position is not found. In the general case, two checks are performed: whether the value matches the property, and then recursively searching through the list. Two approaches are presented: one starting from the beginning of the list (bottom-up) and another from the end (top-down). Both implementations involve recursive calls to search for the desired result.
