Ok, I understand.
But as since bug http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=3154 we can choose the number of records used to build facets (pref maxRecordsForFacets), maybe for some (not all...) libraries it could be good to sort facets results by decreasing occurences order. Would you agree a syspref for that ?

Regarding the facets themselves (not the results), I think they are sorted according to decreasing occurences order. That's why they are not always in the same order. It sounds strange for me.
C4/Search.pm
515                 for my $link_value (
516 sort { $facets_counter->{$b} <=> $facets_counter->{$a} }
517                         keys %$facets_counter )

Facets used to be sorted on popularity, but that was confusing people because the numbers weren't showing. I did some Amazon and Kohls shopping this weekend and the facets were sorted alphabetically when it came to things like brands. The problem is that Koha doesn't use all pages of results to figure out the facets and popular sites do! So if we only use the first page of the results we can't show true popularity and so I think that's why it was changed to alphabetical a while back.

    Hello
    Could some librairians and vendors tell me if they like the way
    Koha is sorting facets and facets results, on a UX point of view ?

    Currently,
    - Results for each facets are sorted alphabeticly.
    - I can't explain the way factets (Authors, Title, Topics...) are
    sorted, maybe by popularity, but it is not always the same,
    depending of the request !

    If we look at other catalogues, or non library websites
    (Amazon...), we don't see the same behavior.
    - Facets sorting does not change in the same catalogue
    - Facets results are sorted according to popularity (decrescent
    occurences), or sometime in a predefined order, sometime both, but
    never alphabeticly.
    (in amazon.com <http://amazon.com> , Author and Book series are
    sorted according to popularity order, but Departement and Format
    facets in a predefined order. cf.
    
http://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Dstripbooks&field-keywords=game
    
<http://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Dstripbooks&field-keywords=game>
    in worldcat, Content and Public in a predefined order, and the
    others by popularity :
    http://www.worldcat.org/search?qt=worldcat_org_all&q=proust
    <http://www.worldcat.org/search?qt=worldcat_org_all&q=proust> )

    If you agree, I can make a patch for sorting facets results by
    popularity (easy to do) and sorting facets according to a defined
    order (more complicated for me but I will try...).
