            Bug ID: 30883
           Summary: Authorities merge is limited to 100 biblio with
                    Elasticsearch
 Change sponsored?: ---
           Product: Koha
           Version: master
          Hardware: All
                OS: All
            Status: NEW
          Severity: critical
          Priority: P5 - low
         Component: Searching - Elasticsearch

In C4::AuthoritiesMarc::merge, we search all biblio records using an authority
with Koha::Authorities->linked_biblionumbers().
This method uses simple_search_compat() with no results limit, even saying in
comment :
# if max_results is undefined, we will get all results
https://git.koha-community.org/Koha-community/Koha/src/commit/44d6528b566e5c16eba9b15f8aa24667293766c3/Koha/Authorities.pm#L80

With Zebra searchengin it is correct.

But not with Elasticsearch, there is an hardcoded limit at 100 in case no limit
is given :
https://git.koha-community.org/Koha-community/Koha/src/commit/44d6528b566e5c16eba9b15f8aa24667293766c3/Koha/SearchEngine/Elasticsearch/Search.pm#L346

This means authorities links are wrong after a merge or an edit in case the
authority is used in more than 100 biblio records.

:(
