[Koha] Sorting order in Koha result list

[Katrin Fischer]

Hi Michael,

I don't know how to fix it, but looking into it a long time ago I
figured out that Koha uses only 245$a for sorting on Title and filed a
bug report to improve this behavior:

*Bug 15161*
<https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=15161> -
Sorting by Title does not include volume/part information from $p and $n

What you might see happening is that Koha sorts by biblionumber, when
the first sorting criteria is the same for multiple records.

Hope this helps,

Katrin
