Dear List, We are running Koha 16.05.02 on Debian 8, installed from packages, with unimarc flavor and koha's xslt set to off. As we are gradually building our authorities’ thesauri, we would like subject searches from records to behave as keyword subject searches and include records with terms not yet confirmed as authorities. Thus, under Administration in System preferences/Authorities preferences/General we have set UseAuthoritiesForTracings to "Don't use" authority record numbers instead of text strings for searches from subject tracings. However, when a subject search is prompted from a record, it returns only records linked to the specific authority number (an) subject term, and fails to return biblios with similar plain subject keywords (with no "an") E.g. If in a biblio record, we click on Russia (an:3320, unimarc field 607a), it will only return records that have this geographical term (in unimarc field 607a) as an authority (an:3320), and no records that include such term as a simple non-authority keyword (in unimarc field 610a). Somehow, the system preference change has no effect. Our case seems similar to the one described in an earlier post by Francois Charbonnier ( https://lists.katipo.co.nz/public/koha/2014-October/041177.html), and possibly remained unresolved. Any guidance/assistance to what might be causing such behavior will be very much appreciated. Kind regards, Andreas Roussos Systems Administrator Holy Monastery of the Paraclete
