Two level indexing
When using two level indexing, the image address assigned to
each document is defined as follows:
• Field D (Level 1) defined as having a field length greater than 0.
• Field C (Level 2) defined as having a field length greater than 0.
• Fields B and A may be defined as fixed fields if desired.
For example, if you scan a book with 2 chapters (Chapter 1 has
40 pages and Chapter 2 has 60 pages) the image address has
been defined:
• Field D has 3 characters
• Field C has 2 characters
• Field B has 0 characters
• Field A has 0 characters

The header page for Chapter 1 is assigned image address
01.000. The first page of Chapter 1 is assigned image address
01.001; the second page is assigned image address 01.002, and
so on through Chapter 1.
The header page for Chapter 2 is assigned image address
02.000. The first page of Chapter 2 is assigned image address
02.001; the second page is assigned image address 02.002, and
so on through Chapter 2.
Any one of the pages may later be located and retrieved using its
unique image address.
