[Scripter] describes a model of the user search process that goes beyond the user interface, and describes the overall user interaction with the search process. Quesenbery identifies five approaches to information: browse, find, query, structured, guided. The purpose of the model of how people search is to design more “effective and usable search.” The user interaction is described as six steps: formulates a question, create the query, review the results, evaluate the likelihood of success, select and examine an item, and evaluate success.
