Abstract
The invention provides a method and system for hierarchical search retrieval. The method includes performing a text search on a hierarchy data structure of information. Forming a limited size hierarchy data structure using the search results. Assigning a location number for each search result in the hierarchy data structure. Sorting the hierarchy data structure. Clustering the sorted hierarchy data structure by categorizing the search results in the hierarchy data structure into groups that are related based on proximity. Limiting a hierarchical depth for each group in the clustered hierarchy data structure based on a configurable depth value to reduce hierarchical results for presentation. Providing the clustered hierarchical data structure as a list of search results as output.
