Two level offset indexing
When using two level offset indexing, the image address assigned to
each document is defined as follows:
• Field D (Level 2) defined as having a field length greater than 0.
For example, if you scan a book with 2 chapters (Chapter 1 has 40
pages and Chapter 2 has 60 pages), and the image address has
been defined as:
• Field D has 2 characters
• Field C has 0 characters
• Field B has 0 characters
• Field D has 0 characters
The header page for Chapter 1 is assigned image address 01. The
remaining pages of Chapter 1 are also assigned image address 01.
The header page for Chapter 2 is assigned image address 02. The
remaining pages of Chapter 2 are also assigned image address 02.
Either one of the chapter header pages may later be located and
retrieved using its unique image address. Pages within a chapter may
be located and retrieved by first finding the chapter header and then
manually scrolling through the remaining pages of the chapter.
