Three level offset indexing
When using three 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 greater than 0
∙Fixed field may be defined, if desired
For example, if you scan a book with two sections (Section 1 contains 2 chapters, each having 40 pages; Section 2 contains only 1 chapter, having 120 pages) the image address has been defined:
∙Field A has 0 characters
∙Field B has 2 characters
∙Field C has 1 character
∙Fixed field has 0 characters
