Abstract
Abstract A method stores, indexes, searches and retrieves data information in a large data storage and retrieval system. Large amounts of data information, subject to searching and retrieval, are broken down and stored in sub-collections. Each sub-collection separately performs indexing of only the data information contained within that sub-collection and forms an inverted index. Statistical information derived from the inverted index of each sub-collection is collected by a global collection custodian and compiled into a global index. The global index is then passed to each sub-collection and is used by each during searching and retrieving of data information. Search results from each sub-collection are passed to the global collection custodian and organized there before being passed to a system user.
