https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=33159 --- Comment #4 from Frank Hansen <frank.hansen@ub.lu.se> --- Nick, I have almost the same thought. Koha hardcodes non-6XX fields to use LCSH (in C4/Header/MARC21.pm). But actually, Thesaurus searches are only relevant for 6XX fields. So I would like to limit thesaurus searches to be done on 6XX fields only. In addition to this, we get problems if thesaurus searches are performed, because our non-6XX authority records that arrives from Libris (Royal Library of Sweden) are coded as "|" (No attempt to code) in 008/11, which means that e.g. personal names cannot be linked unless they are lcsh. So therefore have made the following change: - if ( $thesaurus ) { + if ( $thesaurus && $self->{field}->{_tag} =~ m/6../ ) { It would work for us. But I don't know if it has other consequences.
