    (b) generating a filter network comprising a plurality of filter nodes, wherein the structure of the filter network corresponds to the logical structure of the query;

    (c) optimizing the structure of the filter network by identifying pairs of redundant filter nodes in the filter network and deleting one of the redundant nodes in the pair; and

    (d) optimizing the display of the filter network by identifying similar sub-networks in the filter network and merging the sub-networks.
