The Flamenco Search Interface: "We are creating a search interface framework, called Flamenco, whose primary design goal is to allow users to move through large information spaces in a flexible manner without feeling lost. A key property of the interface is the explicit exposure of hierarchical faceted metadata, both to guide the user toward possible choices, and to organize the results of keyword searches. The interface uses metadata in a manner that allows users to both refine and expand the current query, while maintaining a consistent representation of the collection's structure."
