Abstract

A system and method for flexible indexing of document content for facilitating the rapid search and retrieval of large collections of documents. The method for flexible indexing of document content includes obtaining a collection of documents to be indexed, storing the collection of documents in a single document information stream, parsing each one of the documents into constituent words to facilitate indexing, creating a plurality of stem words to be indexed by stemming each word into a standard prefix; and indexing each stem word. Stem words may be indexed character-by-character based on character frequency, into either primary or secondary fixed-size records or secondary overflow records. Each stem may be terminated by a translation vector record number. Document locations may be accessible through the translation vector record number. Translation vector entries specify each stem word's location by stream identification number and record number. Locations may be grouped by count in streams of fixed-size records.
