            Bug ID: 31023
           Summary: Cannot create new GENRE/FORM authorities when
                    QueryRegexEscapeOptions  set to 'Unescape escaped'
 Change sponsored?: ---
           Product: Koha
           Version: master
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P5 - low
         Component: Searching - Elasticsearch
          Assignee: koha-bugs at lists.koha-community.org
          Reporter: nick at bywatersolutions.com

Bug 24286 and bug 24264 added some escaping for the forward slash in this
authtype, however, when we unescape escaped characters for regex, it appears we
break the escaping in FindDuplicateAuthority

To test:
0 - Have Koha using Elasticsearch
1 - Set  QueryRegexEscapeOptions to 'unescape escaped'
2 - Attempt to add a new 'GENRE/FORM' authority record
3 - On save you get a 500 error
Unable to understand your search query, please rephrase and try again.
