Abstract: A system for searching through documents maintained in electronic form is described. The system is capable of searching through individual documents, or groups of documents. In the case of a group of documents, the system operates by locating one or more hit entries in a group hits table associated with a keyword in a search request. Each of the located hit entries corresponds to a different document in which the keyword appears. The system extracts from the located hit entries hit information indicating the number of times the keyword appears in documents respectively associated with the located hit entries. This hit information is presented to a user, and a command identifying one of the documents respectively associated with the located hit entries is received from the user. The system then locates one or more location entries in a document index table associated with the identified document.

Abstract: The present invention provides a method and apparatus for extracting, synchronizing, displaying, and manipulating text and image documents in electronic form for display. In the Preferred embodiment of the present invention, text and image files for documents, such as for example patent documents, are initially stored on separate magnetic tape media. These data files are extracted from the respective tapes and placed onto a faster medium, such as a hard disk drive. The text and image files are synchronized to produce Equivalent Files using heuristic algorithms to create an approximate equivalence relationship between the text and the image files. The Equivalent Files and image files residing on, for example, a hard disk drive or compact disk (CD), are coupled as a resource to a computer display system.
