Bug ID: 41795
Summary: UNIMARC: a Zebra search for Corporate Body Name
authorities will also return Collective Titles

As per the Bug Summary, when you search for Corporate Body
Name authorities (authtypecode 'CO') in the OPAC or in the
Staff interface, the results will also include Collective
Titles (authtypecode 'CO_UNI_TI').
The problem manifests in UNIMARC instances that use the
default authority type codes and a Zebra search backend.
AIUI, it has to do with 'Corporate Body Name' authorities
using an authtypecode ('CO') that just so happens to be
the prefix of another authtypecode ('CO_UNI_TI') used by
'Collective Title' authorities.
Out of the box, MARC21 instances aren't affected by this.
However, in the (unlikely?) scenario that you've decided
to catalog authorities under different authtypes than the
built-in ones and somehow managed to add new authority
types that share the same prefix ('AUTH', 'AUTH_CORP',
'AUTH_PERS', etc.), then you will run into problems when
searching as there will be no guarantee that filtering
for the specific authority type 'AUTH' will return only
the results you will be expecting.
Elasticsearch is not affected -- it's a Zebra-only thing.
