the list, and/or choose a barcode/OCR formula (these are set up
using the Barcode/OCR section).
To define the formula, refer to: Project setup, Indexing, Defining
value formulas.
Minimum Length : define the minimum number of characters to be
contained in the value. If the value does not contain the minimum
number, it will be considered as invalid by the software and will be
highlighted in red in the
Index pane. It will thus not be possible to
process (export) it.
Input mask : define the format of the value. If the value does not
have the given format, it will be considered as invalid by the
software and will be highlighted in red in the
Index pane. See:
Project setup, Scanning, Barcode/OCR, Setting a mask syntax.
Output mask : define the format into which the value must be
converted when producing index files during processing.
Advanced tab
The options available in this tab are used to set multiple value
fields, with possible multi selection. You can indeed connect a field
with an external database or with a list of valid values. If the data
extracted from the documents does not correspond to one of the
(database) values, the index field will be considered invalid by the
application and appear in red in the
Index pane.
DataLink : type in the database name, i. e. the one that has been
defined in the DataLink tab. See: Project setup, Indexing, DataLink.
