Abstract

An improved method and system for storing and retrieving information written as text. The method and system store most words of the text solely in an inverted structure, and the remainder of the text's information in an auxiliary structure. The structures can be quickly searched for keyword information, provide highly efficient storage, and can be reconstituted into the original text.
