The patent describes a method for indexing, retrieving, organizing, and describing documents in an information retrieval system, primarily focusing on the use of phrases. It innovates by identifying phrases that predict the presence of other phrases in documents, allowing documents to be indexed based on these identified phrases. The system also identifies related phrases and extensions, utilizes phrases in queries to retrieve and rank documents, clusters documents in search results, generates document descriptions, and removes duplicate documents from search results and indexes.
