The patent describes an information retrieval system that uses phrases instead of individual words to index, search, and rank documents. Phrases are identified based on their frequency and ability to predict other phrases within a document. The system includes a primary index for storing high-relevance documents in rank order and a secondary index for additional documents sorted by document order. This approach aims to improve the precision and relevance of document retrieval by focusing on semantically significant phrases.
