Abstract
A computer system and method for information indexing and retrieval. The full text index can searchably accommodate linguistic, phonetic, conceptual, contextual and other types of relational and descriptive information. The full text index is created in two phases. In the first phase, a word list symbol table, an alphabetically ordered list and a non-repeating word number stream are constructed from the source text. In the second phase, a word number access array and in-memory full text index are constructed and then index data is merged into the final index.
