Many different solutions have been proposed to the general information seeking task of users, but few if any have addressed the needs of individuals or have leveraged the benefit of single-user interaction. The Haystack project is an attempt to answer the needs of the individual user. Creating such a system requires solving two problems. Half the problem addresses the manipulation of the data into a queryable format. Once the user's information is represented in Haystack, the other half of the problem centers around our desire to answer the highly varied questions a user may ask about this information. In this thesis we will propose a means of representing information in a robust model within Haystack and we will describe a corresponding mechanism by which the diverse questions of the individual can be answered. This novel method functions by using a combination of existing information systems. We will call this combined system a hybrid-search system.
