I'm working on a design of iOS app. It allows to search some restaurant typing the street or city. If one wants to refine this search, there are some filters (like kitchen, medium price, ticket restaurant and so on), which are opened in another page.
According to Nielsen's principle of visibility of system status, do you think that after the refining of the search with some of these filters it is necessary to have in the result search page (the page which shows all the results based on the search) something that reassumes all the active filters? Or it isn't worth because a user knows what his filtering was, and he doesn't need a direct feedback like this?
