Three level indexing
When using three level indexing, the image address assigned to each
document is defined as follows:
• Field A (Level 1) is defined as having a field length greater than 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 3 characters
• Field B has 2 characters
• Field C has 1 character
• Fixed field has 0 characters
