Two level offset indexing When using two level offset indexing, the image address assigned to
each document is defined as follows:
∙Field A (Level 1) is defined as having a field length of 0
∙Field B (Level 2) is defined as having a field length greater than 0
∙Field C (Level 3) is defined as having a field length of 0
∙Fixed field may be defined, 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 A has 0 characters
∙Field B has 2 characters
∙Field C has 0 characters
∙Fixed field has 0 characters
