Description Nick Clemens (kidclamp) 2023-09-07 17:04:54 UTC 
If an authority record is modified in any way, we trigger a merge to update all biblios using the authority.

This also happens if we merge a duplciate authority into one that is in use, all biblios already attached to the correct authority are updated.

If the heading or controlled indicators or thesaurus have changed, this makes sense, but if not, we are triggering many biblio modifications and reindexes that are not needed.

We also need to consider the case where a See-From is is added and IncludeSeeFromInSearches is enabled

There is a development about adding URIs from 024 in auth to bib record when merging. A Biblibre report, forgot the number. This would be an exception.
