摘要:
A method and apparatus for indexing and searching content in a hardcopy document utilizes a searching assistant computing device (402) with an index table (420) stored in memory (412). The index table (420) is created in memory by scanning a 2-D barcode from a hardcopy document or alternatively by downloading indexing information from a web page via the Internet (430). A search engine (410) in the searching assistant (402) searches the index table (420) to locate a data element found in the content of the hardcopy document. The indexing information corresponding to the data element is displayed to a user as part of the search results to indicate the location of the data element in the hardcopy document.
