Periscope search might be (too) slow as soon as we start dealing with more data, that is, many suppliers and many results per supplier. We should make sure that overall response time of a search stays within acceptable bounds - which should be at the magnitude of ~0.1 seconds to feel instantaneous for the user, or at least sub-second.

• Limit the maximum number of items listed per supplier (e.g. 5 items) and as many suppliers as to be expected in a typical customer setup.
