First Claim
Patent Images
1. A method of filtering a key-word search of a universe of documents wherein the universe comprises a plurality of regions, the method comprising the steps of:
- creating a first region-set identifying regions in the universe satisfying a first criterion;
creating a second region-set identifying regions in the universe satisfying a second criterion;
creating a third region-set from said first and said second region-set in accordance with a third criterion; and
presenting as results documents from regions of said third region-set.

Abstract
A method improves a search in a hierarchical structure by focusing the search to selected regions within the structure. The method defines one or more region-sets and uses the region-set(s) as either a filter for the results of a key-word search or an integrated part of a search engine to increase the efficiency of the search engine. The method also provides for dynamic creation of new region-sets from existing region-sets using a prescribed set of operators.

5. A method for searching a hierarchically structured information space, wherein the space is divisible into a plurality of regions, the method comprising the steps of:
-
defining a first set of regions which satisfy a first criterion; defining a second set of regions, which satisfy a second criterion; creating a third set of regions from said first and second set of regions; receiving a search query including at least one key-word; and searching said information space for documents matching said key-word and being located in a region in said third region-set; and presenting results indicating documents found in said step of searching. - View Dependent Claims (6, 7)

8. A method for searching for documents in a hierarchically structured information space that includes a plurality of nodes of differing hierarchical levels, wherein a particular document region for a given node corresponds to all documents at nodes for which said given node constitutes a root, the method comprising the steps of:
-
defining a first set of regions, said first set comprising pointers to a first plurality of nodes wherein the first plurality of nodes are logically related in accordance with a first criterion; defining a second set of regions, said second set comprising pointers to a second plurality of nodes wherein said second plurality of nodes are logically related in accordance with a second criterion; creating a third set of regions, said third set comprising pointers to a third plurality of nodes, wherein said third plurality of nodes are logically related to said first plurality of nodes and said second plurality of nodes in accordance with a third criterion; and searching said space in accordance with a search query and said third set of regions. - View Dependent Claims (9, 10)

11. A method for searching for documents in a hierarchically structured information space that includes a plurality of nodes of differing hierarchical levels, wherein a particular document region for a given node contains all documents at nodes for which the given node constitutes a root, the method comprising the steps of:
-
defining a first set of regions, said first set comprising pointers to a plurality of nodes which are logically related in accordance with a first criterion; receiving a search query including a keyword; and searching the information space using the search query and the first set of regions. - View Dependent Claims (12, 13, 14)

15. A method of searching for documents on the world wide web, the method comprising the steps of:
-
receiving from a user a search query that includes at least one key-word and an operation criterion; defining a first list of URLs corresponding to nodes satisfying a first criterion; defining a second list of URLs corresponding to nodes satisfying a second criterion; defining a third list of URLs using said first list and said second list and said operation criterion; and identifying to the user documents matching said key-word and containing a URL from said third list, wherein said first and second criterion are predetermined.

16. A method of searching for documents on the world wide web, the method comprising the steps of:
-
receiving from a user a search query that includes at least one key-word and an operation criterion; defining a first list of URLs corresponding to nodes satisfying a first criterion; defining a second list of URLs corresponding to nodes satisfying a second criterion; defining a third list of URLs using said first list and said second list and said operation criterion; and identifying to the user documents matching said key-word and containing a URL from said third list, wherein said first and second criterion are based on the contents of said search query.
