The problem
Site visitors expect to find the information they are looking for within seconds. Besides a good information architecture, and top tasks, it is important that the search experience is built in such a way that site visitors expect.
They have become used to a google like search experience, a traditional keyword-based search doesn’t cut the deal anymore.
People don’t simply search for information; they are looking for an answer for their problem. We must switch to a problem-based search instead of keyword based.
