Under one aspect, an interface program stored on a computer-readable medium causes a computer system 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 set of document-location tuples from a corpus of documents, each document-location tuple satisfying the search criteria from the user, each location having associated cartographic display attributes; displaying a visual representation of the domain having an average spatial scale; selecting a subset of the set of document-location tuples based on the cartographic display attributes and on the average spatial scale of the visual representation of the domain; and displaying a plurality of visual indicators representing the selected subset of document-location tuples.
