[Koha-devel] How is relevance weighted in zebra search?

[Francois Charbonnier]

Hi,

I'll suggest you to read this and that :
http://bywatersolutions.com/2012/11/27/a-little-bit-about-relevance-in-koha/
https://lists.katipo.co.nz/public/koha/2012-February/031909.html

Both helped me to understand a bit more how relevance works in Koha.

And, try to desactivate the QueryAutoTruncate system preferences. It 
doesn't mix well with the relevance ranking.
