Abstract
Document texts are produced by recognizing characters in document images by an Optical Character Recognition (OCR) process. When such a document text matches one or more search terms of a query, the corresponding document image is displayed. Regions of the document image, corresponding to words of the document text that match the search terms, are displayed in a visually distinctive manner. The display of the document image may be augmented by displaying a region corresponding to a reference text within the document text in another visually distinctive manner.
