Recognition systems can interpret a wide variety of fonts. The accuracy of some systems can be improved by training them to recognize particular fonts and the specific characteristics of the documents. A basic reason to convert paper documents into electronic files is to improve access to the information. Indexing and the creation of a fulltext retrieval database is one possibility. As the name implies, a fulltext database allows you to search the entire text of a document.
Every word is indexed for rapid retrieval.
Often, the index takes up as much space as the text. Storage media like CD-ROMs with over 600Mb of available space are perfect for these types of databases. However this involves the classic trade-off between speed and space. Assemble all text into a common area, such as a single directory. Identify and possibly mark up, in any required format, the headings, sections, and subsections that provide a hierarchical structure to the document.
