Catalog Search Relevance Ranking
Can anyone point me in the direction of a resource that will explain how Koha determines relevance in catalog searches? Some of my libraries have been asking about it since it's the default sort option.

Hi Joel
Can anyone point me in the direction of a resource that will explain how Koha determines relevance in catalog searches? Some of my libraries have been asking about it since it's the default sort option.
I would suggest to start, as usual, with the Koha manual: * https://koha-community.org/manual/17.05/html/13_searching.html The actual relevance ranking is done within Zebra, you will find the "Zebra - User's Guide and Reference" here (unfortunately the link to this guide in the Koha manual is dead): * http://www.indexdata.com/zebra/doc/ For relevance ranking start here: * http://www.indexdata.com/zebra/doc/administration-ranking.html Hope this helps.

Hi Michael and all, please report any problems with the manual that you spot or know of. We have a pad that you can just type into, no registration required: https://annuel2.framapad.org/p/KohaManualTodo Also feel free to submit a patch directly, instructions are here: https://wiki.koha-community.org/wiki/Editing_the_Koha_Manual You can also send us text directly to format and include. I would love if we could add more information about how the relevance ranking works! Katrin

If this makes your head swim, try reading the first couple of paragraphs (only!) in the Wikipedia article on TF-IDF document ranking: https://en.wikipedia.org/wiki/Tf–idf That URL contains non-ASCII characters, so it might be problematic; if it doesn't work, try this: https://en.wikipedia.org/wiki/Tf%E2%80%93idf Paul. -- Paul Hoffman <paul@flo.org> Systems Librarian Fenway Library Organization 550 Huntington Ave. Boston, MA 02115 (617) 442-2384 (FLO main number)
