Under one aspect, an interface program stored on a computer-readable medium causes a computer system with a display device to perform the functions of: accepting search criteria from a user, the search criteria including a free-text query and a domain identifier, the domain identifier identifying a domain in a metric vector space; in response to accepting the search criteria from the user, obtaining a plurality of sets of document-location tuples from a corpus of documents, each document-location tuple satisfying the free-text query and a subdomain identifier identifying a subdomain within the identified domain; displaying on the display device a visual representation of the domain identified by the domain identifier; and displaying a plurality of visual indicators representing the document-location tuples.
