           Summary: link_bibs_to_authorities.pl doesn't work with
                    Elasticsearch
 Change sponsored?: ---
           Product: Koha
           Version: master
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: blocker
          Priority: P5 - low
         Component: Searching - Elasticsearch

We need to run the script on daily basis to link bibliographic records to
matching authority records. We know this worked with Zebra. But with
Elasticsearch it don't.

Our current system preference settings is the following:

AutoCreateAuthorites: no. 
BiblioAddsAuthorities: no. 
UseAuthoritiesForTracing: yes. 
CatalogModuleRelink: yes. 
LinkerKeepStale: yes. 
LinkerModule: Default. 
LinkerOptions: broader_headings 
LinkerRelink: yes

In the future we want to AutoCreateAuthorites when matching authority headings
does not exist.

The link_bibs_to_authorities.pl runs normally with no errors but no
bibliographic records are linked to matching authority records. Here is tha
last reports:
