Previous: Thesis Overview
In this chapter we will review previous efforts in information system
research that may prove useful for the type of hybrid-search
capabilities we will attempt in Haystack. Specifically, we will
approach the previous work from four directions: unstructured search
technologies, structured search technology, associative search
technology, and current hybrid solutions. Finally, in
Section 
we will discuss the two primary
building blocks for this thesis, Haystack and Lore.
