    摘要: A displayable digital document such as a .PDF document is indexed by displaying it on a viewer. A database field is provided in a relational database. A user selects a field in the digital document for indexing using a pointing device and defines a bounding rectangle for this field. Offsets are recorded and compared to other bounding rectangles. Comparisons are recorded in a parameter file for each document. An indexer is run to insert the offsets and other data into the relational database and also store the digital image in the relational database. A query is made of the database and part or all of the digital document is displayed based on the results of the query.
