Abstract
A search system may use a stateful session that suggests new keywords for refining a search with each iteration of a search sequence. The keywords may be derived from a set of previous search results, or may be identified from a taxonomy of terms. A user may be able to select the keywords to include or exclude from a user interface to further refine the search. In some embodiments, the user interface may also include various metadata parameters to include or exclude. The system may use one or more conventional query-based search engines and may be implemented as a client application, intermediate service, or as part of a search engine.
