[OPEN-ILS-DOCUMENTATION] Barcode Completion Docs - Barcode formats

[Josh Stompro]

Thomas, Thank you for the feedback.  I've updated the documentation to include a beginning paragraph that addresses the scenario you mentioned, and an example for matching a barcode of any length with a prefix and suffix.  Please let me know if you think I covered it sufficiently.

No padding character or zero length means "attach prefix/suffix to input and look that up".

That may be useful for things like adding a single character to the front of scanned barcodes, regardless of length, such as when migrated/imported data may contain a leading or trailing character. Or both.


Possible examples with length set to 0 and/or padding not set:

Prefix of "a" and suffix of "b" when a barcode scanner was previously outputting those characters around the barcode.

Prefix of "d" because migrated data includes that character but new scans will only include the digits.


Note that "Want to fill out to 14 digits" and "want to check if it exists with a d in front" at the same time could require three rules.  
One for "add the d regardless of what was entered", one for "fill out to 14 digits without a d", and one for both (length 15, prefix has the d in front of whatever the normal prefix is from filling out to 14 digits).
