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.

Hi,

We just upgraded a library from Koha 3.0 to 3.22. After the upgrade, the library complained that the title "Golden Age" was at the bottom of their OPAC search results.

I checked the obvious first:

OPACdefaultSortField had been set to 'relevance' with OPACdefaultSortOrder set to 'ascending', which would definitely be backwards (least relevant first)... I changed to to 'ascending', and got exactly the same results.

Restarting memcache didn't help.

When I searched using yaz-client, I found that the results that were coming first in the list had the phrase "golden age" in 520$a.

Here's the version of zebra:

    $ idzebra-config --version
    2.0.59

At this point, I have two major questions:

1) Where do I check which fields are ranked more highly in a relevance search? (I would think that title should be ranked higher than 520$a -- summary). 2) Why didn't the sort order change when I changed OPACdefaultSortOrder from ascending to descending?
