Hello group members, I am facing problem in koha search through subject terms in librarian and user interfaces. For example, If i want to see books on 4th subject term by clicking on the hyperlink(i.e. wave propagation) than koha merge all previous terms with 'and'. Example mentioned in below line: http://--------/cgi-bin/koha/opac-search.pl?q=su:Engineering and su:Electrical engineering and su:Satellite communication and su:Wave propagation Koha has to make query term as below for proper searching: http://--------/cgi-bin/koha/opac-search.pl?q=su:Wave propagation Please help to resolve the issue, so that koha consider each term as individual entry rather than automatically combining all previous terms with 'and'. Regards, Iftikhar Ahmed.
