Abstract: A database of entries, such as Web pages and sites, is provided. The entries are at least partially mapped to a set of predetermined categories. The entries are also associated with keywords, for instance, by automatic indexing of documents. In response to a query into the database, a user is provided with a series of refinement strategies, in addition to search results. Refinement strategies comprise categories relevant for the search, selected among the set of predetermined categories. Refinement strategies also include keywords dynamically selected among keywords associated with the entries. The user may easily navigate among the results to the query, and formulate new queries.
