public class AdvancedSearch
extends AbstractSearch
implements org.apache.cocoon.caching.CacheableProcessingComponent

Perform an advanced search of the repository. The user is presented with three search parameters, that may be ORed, ANDed, NOTed together. At the present time only three fields are displayed however if the theme whishes to expand this they can do so by setting the num_search_fields to the desired number of search fields. Also, the theme can change the number of results per the page by setting results_per_page FIXME: The list of what fields are search should come from a configurable place. Possibly the sitemap configuration.
