Hi. I mentioned we also have a problem with linking bibs to authorities. We use authorities and want to link them to bibs. Over previous versions of Koha this has sometimes worked quite well. However on a few systems we have at version 3.12 it seems that the Zebra search into the authorities (used by link_bib_to_authorities) is returning all terms that contain any of the words in the bib field. So if the linkage is set to "default" then most authority searches will return multiple answers which means they do not link. If the linkage syspref is set to first or last then most of the bibs will link to the wrong authority as it is pot luck which will be first (or last) of the many authorities found by searching all the words ORed together. The only terms that will link are single-word authorities that are not used in any other authorities. If anyone has any pointers or knows how to get round or over this problem I would love to hear from you. More details on request... We are using Zebra dom indexing and icu chains and are using Koha 3.12 on Debian. We are not yet using QueryParser.
