[Koha] Use of indicators in field 245

[Ere Maijala]

Hi,

Even if leadign article or other nonfiling characters can be handled
pretty well in modern search engines, it's worth noting that it's not so
straight-forward for sorting or any left-anchored searches. Like you
mentioned, we should always keep in mind that MARC records can be
exchanged between systems, and not all are created equal. In my
experience any deviation from standards comes back to bite you at the
latest when you switch systems.

Regards,
Ere
