Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
123 words
A method of searching for documents on the world wide web, wherein a region in the web defines a space for a group of related documents, the method comprising the steps of: defining a plurality of static region-sets wherein each static region-set comprises a plurality of regions in the web and wherein the regions in a given static region-set satisfy a particular criterion; and in response to a search request containing at least one key-word, creating a new region-set from two static region-sets in accordance with an operation criterion; searching the web using the new region-set and at least one key-word; and presenting as a result documents that match at least one key-word and are contained in a region within said new region-set.
Claim 2
Independent Claim
123 words
A method of searching for documents on the world wide web, wherein a region in the web defines a space for a group of related documents, the method comprising the steps of: defining a plurality of static region-sets wherein each static region-set comprises a plurality of regions in the web and wherein the regions in a given static region-set satisfy a particular criterion; and in response to a search request containing at least one key-word, creating a new region-set from two static region-sets in accordance with an operation criterion; searching the web using the new region-set and at least one key-word; and presenting as a result documents that match at least one key-word and are contained in a region within said new region-set.
Claim 3
Dependent Claim
14 words
A claim depending from claim 1 wherein new region-set is used as a pre-filter.
Claim 4
Dependent Claim
14 words
A claim depending from claim 1 wherein new region-set is used with search engine.
Claim 5
Independent Claim
91 words
A method of searching for documents on the world wide web, the method comprising the steps of: 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; receiving from a user a search query that includes at least one key-word; defining a third list of URLs using said first list and said second list and a third criterion; and identifying to the user documents matching said key-word and containing a URL from said third list.
Claim 6
Independent Claim
91 words
A method of searching for documents on the world wide web, the method comprising the steps of: 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; receiving from a user a search query that includes at least one key-word; defining a third list of URLs using said first list and said second list and a third criterion; and identifying to the user documents matching said key-word and containing a URL from said third list.
Claim 7
Independent Claim
56 words
A method for creating a search filter, comprising the steps of: 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, and defining a third list of URLs using said first list and said second list and a third criterion.
Claim 8
Independent Claim
56 words
A method for creating a search filter, comprising the steps of: 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, and defining a third list of URLs using said first list and said second list and a third criterion.
