Do you like the way Koha is sorting facets and facets results ?
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 , 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 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 ) 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...).

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.

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 ) Mathieu Saby Nicole Engard a écrit :

Yes if you change sorting it should be controlled by a preference because even though we have a preference to show facets based on more results it's not feasible for most libraries because it slows things down way too much. Nicole
I knew facet building could slow down opac and staff search, but I did not make tests before... If I suppress all the facet building code in Search.pm, opac results take 2 seconds to show up on a big search (>5000 results) Without any code suppression, and maxRecordsForFacets=4000, it takes 7-8 seconds With maxRecordsForFacets=2000, 4-5 seconds With maxRecordsForFacets=1000, 3-4 seconds With maxRecordsForFacets=500, 2-3 seconds. So 500 is maybe a good value for some libraries (I tested with a small virtual machine) M. Saby Nicole Engard a écrit :

The change was in Bug 4891, Order facets in left sidebar of search results (http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=4891) but you can find more discussion in its duplicate, Bug 2614, Facets in Alpha Order (http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=2614). -- Owen -- Web Developer Athens County Public Libraries http://www.myacpl.org
What constitutes 'popularity'? I have a feeling this is a useless sort order for a research collection like ours that doesn't loan out anything. Good old fixed data like name, title, date are what suits our readers best. Elaine On Mon, Nov 19, 2012 at 1:00 PM, Mathieu Saby <mathieu.saby@univ-rennes2.fr>wrote:

Popularity in the case of facets occurs to the number of times a particular value occurs in the set being used to build facets. It has nothing to do with circulation popularity.
