Search: The Purest Form of Interaction Design

The document is a presentation about search and interaction design. It discusses how search has evolved from just putting a search box on a site to being a complex interaction design problem. It covers how search engines work through crawling, indexing, and algorithms. It also addresses the differences between enterprise search, used by customers and employees within an organization, compared to public web search engines. The presentation emphasizes that search is about understanding user intentions and providing choices, and that designers need to focus on the human aspect of search, not just the technical implementation.
