20. The method of claim 1 , wherein the domain identifier is a word or phrase corresponding to a location.

21. The method of claim 1 , wherein the domain identifier is spatial criteria entered into a spatial criteria entry control.

22. The method of claim 1 , wherein the domain identifier is a map.

23. The method of claim 1 , wherein the domain identifier is a map border of a multi-dimensional representation of a domain displayed on the display device.

24. A method for displaying information about documents in a corpus of documents, said method comprising:

accepting search criteria from a user, said search criteria including a free text entry query and a domain identifier identifying a domain;

in response to accepting said search criteria from the user, identifying a set of documents among the corpus of documents, wherein each document of the set of documents: (1) contains anywhere within the document location-related information referring to a location within the domain; and (2) contains anywhere within the document text responsive to the free text entry query, wherein said identified documents are identified by a plurality of document identifiers;

displaying a representation of said domain on a display device, wherein the domain is a geographical region and said representation is a multi-dimensional map of the geographical region; and

displaying within the representation of the domain displayed on the display device a plurality of icon types, wherein each icon type of the plurality of icon types represents a corresponding different subset of documents among the identified documents and wherein each icon type is positioned within the representation of the domain at a coordinate corresponding to the location-related information for the corresponding subset of documents.

25. The method of claim 24 , wherein icon types among the plurality of icon types have different visual appearances.

26. The method of claim 24 , wherein the plurality of icon types includes a first icon type for representing multiple documents for which the specific locations to which those documents refer are close to each other on the displayed representation of the domain.

27. The method of claim 26 , wherein the plurality of icon types includes a second icon type for representing a single document and wherein the second icon type has a visual appearance different from the visual appearance of the first icon type.

28. The method of claim 24 , wherein the plurality of icon types includes a first icon type for representing multiple documents for which the specific locations to which those documents refer are identical.

29. The method of claim 28 , wherein the plurality of icon types includes a second icon type for representing multiple documents for which the specific locations to which those documents refer are close to each other but not all identical.

30. The method of claim 29 , wherein the first and second icon types have different visual appearances.

31. An interface program stored on a computer-readable medium for causing a computer system with a display device to perform the functions of:

accepting search criteria from a user, said search criteria including a free text entry query and a domain identifier identifying a domain;

in response to accepting said search criteria from the user, identifying a set of documents among the corpus of documents, wherein each document of the set of documents: (1) contains anywhere within the document location-related information referring to a location within the domain; and (2) contains anywhere within the document information responsive to the free text entry query, wherein said identified documents are identified by a plurality of document identifiers;

displaying a multi-dimensional representation of said domain on the display device; and

displaying within the representation of the domain displayed on the display device a plurality of visual indicators as representations of the documents identified by said plurality of document identifiers, wherein each visual indicator of the plurality of visual indicators represents a corresponding different subset of documents among the identified documents and wherein each visual indicator is positioned within the representation of the domain at a coordinate corresponding to the location-related information for the corresponding subset of documents.
