What are some differences between a full search and a limited weapon search and are there any exceptions to either of them?

a search and seizure allows police officers to examine your vehicle or residence for evidence, illegal weapons, or substances. In comparison, a frisk only lets officers pat down someone in order to detect weapons like guns or knives.

Explanation:

Unlike a full search, a frisk is limited to a patting down of the outer clothing. If the officer feels what seems to be a weapon, the officer may then reach inside the person's clothing. If no weapon is felt, the search may not intrude further than the outer clothing.
