Enterprise Search is used by organizations to capitalize on their internal knowledge by providing quick access to all internal information, helping users re-finding and discovering new information, as well as creating the necessary conditions for collaboration across organizational and geographical boundaries. In this large organization a search application was created to meet these goals. This paper focuses on the main design concepts of the second release of the search application, and how these were affected by experiences gained throughout the project. This design focused on simplicity and discoverability. Preliminary results show that the design is usable and that users find it easier to find the information they are looking for. A general increase in user satisfaction is also established.
