Thanks Mason, you've put me on the yellow brick road. I've looked at several config files in the ..../zebradb subdirectory, and am now surrounded by the flying monkeys. :) Best, Doug -----Original Message----- From: Mason James [mailto:mtj@kohaaloha.com] Sent: Monday, January 30, 2012 6:50 PM To: Doug Dearden Cc: koha@lists.katipo.co.nz Subject: Re: [Koha] How or maybe where are relevance rankings established?

Hello All,

I am trying to get a grip on how a search is ordered when "relevance" is specified. Is there a place in the staff client where these results are controlled - i.e. which fields are given weight?

afaik, the relevance is determined in zebra, internally here's some doc.. http://www.indexdata.com/zebra/doc/administration-ranking.html http://www.indexdata.com/zebra/doc/querymodel-zebra.html

Or perhaps the question is where would I find the algorithm that is being used - assuming it is hard coded somewhere?

The "about" info pasted below my name in the event an update will make a difference here.

yes indeed, good thinking :)
