Hi, Working on Bug 26311 I noticed my BDIC join for patrons search was wrong. I changed with a prefetch. I think i found this in existing code : https://git.koha-community.org/Koha-community/Koha/src/commit/8fd2083295af03... Is this correct ? Should be just : { join => 'categorycode' } Like we see in : https://git.koha-community.org/Koha-community/Koha/src/commit/8fd2083295af03...
