摘要：A method stores, indexes, searches and retrieves data information in a largedata storage and retrieval system. Large amounts of data information, subject tosearching and retrieval, are broken down and stored in sub-collections. Each sub-

collection separately performs indexing of only the data information contained withinthat sub-collection and forms an inverted index. Statistical information derived from theinverted index of each sub-collection is collected by a global collection custodian andcompiled into a global index. The global index is then passed to each sub-collection andis used by each during searching and retrieving of data information. Search results fromeach sub-collection are passed to the global collection custodian and organized therebefore being passed to a system user.
