Efficient searching of multi-terabyte archives TextCenter, a series of application programs designed to control and run large numbers of TextFinders in parallel, supports the creation and maintenance of large text archives and manages, schedules and optimizes user retrievals against them. TextCenter contains sophisticated subsystems for managing both retrospective and dissemination searches. In retrospective searching, TextCenter processes queries by comparing them to preloaded databases, in which new information can be added at any time. In dissemination searches, TextCenter maintains a standing set of queries for each user and processes them against incoming data. Users may add, cancel or modify their queries at any time.
Search results are consolidated and returned to each user.
Users may update their active profiles at any time. TextCenter provides facilities to load incoming data onto the TextFinder file systems, and manages all searches of new data against the current user profile database. Text databases and real-time data feeds can now be filtered, disseminated, and searched with unprecedented precision, recall and speed with TextCenter. 2001 Paracel Inc.
