Start with the user interface (UI) and work backwards. That was the advice I shared with search managers developing their existing application or planning a new application during an enterprise search workshop at the recent IntraTeam event in Copenhagen, Denmark. Sinequa recently sent me some examples of user interfaces from its customers (thank you Laurent Fanichet), which showed the variety and inevitable complexity of enterprise search UIs. Too often businesses make a deliberate choice on the technology and give little thought to the UI (so much for the ethos of user-centric delivery!).
