Answer: Internal search
Explanation: When someone like Nakeisha wants to buy something that is different from what she is currently using, but she also used those other products before, so she has experience with those other products. In this case, searching for information concerning known things, i.e things that Nakeisha remembers, is an internal search. So it's a search that relates to things that are stored in memory and such searches begin by recalling known information based on experience from previous searches or shopping actions. In other words, choosing what to buy comes down to familiar things from our memory.
