ABSTRACT:
According to the present invention, apparatus and methods are provided to enable a user to locate and retrieve sets of information relevant to search criteria specified in a search query submitted by the user. Search results include not only a list of information sets matching with the search criteria, but also the preserved structure of any tags used in annotating the information set according to a structured mark-up language such as XML. A user may select a tag from a presented list of the returned tag structures, and the apparatus lists those documents containing the selected tags. The list of tags is then adjusted to include the selected tag and any other of the returned tags contained in the listed documents. Further tag selection from the adjusted list leads to a further refinement of the listed documents, enabling the user to navigate the search results on the basis of tag information.
