Barton told me it could be useful to share this excange I had with IdexData people during the implementation of the Zebra facets. It highlights a limitation on the yaz-client tool, and they suggest we better use zoomsh. I'm not sure if I already posted this on koha-devel, but it doesn't hurt to re-post, and might save some people some hours and headaches.

We'll remove that limitiation. You can use zoomsh instead to play with longer facet specs. / Adam Z> elem zebra::facet::su-to:0:100,su-geo:0:100,su-ut:0:100,au:0:100,se:0:100,itype:0:100,location:0:100,holdingbranch:0:100,homebranch:0:100,tomas:0:100 Z> s 1+1 Sent presentRequest (1+1).

For facets, it would be great that we could ask for n facets, and retrieve all at once. I'll try 2.0.59 in about two hours and reply.

Please reply-all and keep [ZEB-663] contents in the subject line for future conversation. Hi Tomas, we can't see a limit of 8. Asking for more than 8 returns more than 8. And supplying any non-existing facet-field throws an error. What version of Zebra are you using? / Adam / Adam On 02/04/2015 03:59 PM, Tomas Cohen Arazi wrote: Hi, I've been playing with facets retrieval, which shines in Koha 3.18 (thanks!) One thing I noticed is that asking zebra to retrive more than 8 facets at once doesn't work (it only retrieves 8). What i did was:
elem zebra::facet::a1:0:20,...,a8:0:20,bullshit:0:20
('bullshit' doesn't exist on the facet indexes) and
f a s 1+1
shows the expected results. If I do
elem zebra::facet::a1:0:20,...,a7:0:20,bullshit:0:20
It fails ([25] Specified element set name not valid...)
