Hi Zeno: I believe that I've solved the symptom, although I admit that I don't 100% understand the root casue of the problem.
The problem appears to be the line '<retrieval syntax="xml" name="zebra::*" />' in "etc/zebradb/retrieval-info-bib-dom.xml". If you remove that and restart Zebra for your instance, you'll find that you're once again able to use "zebra::index", "zebra::snippet", "zebra::data", "zebra::facet::index:register:count". The in-depth explanation starts here: The vital line really is '<retrieval syntax="xml"/>'. With that line, we have access to the special retrieval elements (http://www.indexdata.com/zebra/doc/special-retrieval.html), as well as the ones that we've defined in the "retrieve pipeline" in /etc/koha/zebradb/biblios/etc/dom-config.xml, such as "zebra", "index", "marc", and "marcxml". (See /etc/koha/sites/libraryname/zebra-biblios-dom.cfg for the reference to /etc/koha/zebradb/biblios/etc/dom-config.xml. Also see http://www.indexdata.com/zebra/doc/record-model-domxml-pipeline.html for an explanation of the pipeline: "The possible multiple <retrieve> pipeline definitions are distinguished by their unique name attributes, these are the literal schema or element set names used in SRW, SRU and Z39.50 protocol queries."). I'm going to guess that the problem arose with YAZ 5.8.1 2015/01/13: "retrieval: pick matched element-set rule YAZ-813" (http://www.indexdata.com/yaz/doc/NEWS). Here's the git commit: http://git.indexdata.com/?p=yaz-moved-to-github.git;a=commit;h=f24766f1e9fc5 404fc0b512af8607d7f7054f4be. I haven't read through it extensively, so I could be wrong, but perhaps it caused some sort of problem where Zebra/YAZ was trying to find "zebra::*" in /etc/koha/zebradb/biblios/etc/dom-config.xml. I'm guessing that it didn't check that it was a special retrieval element and that it failed to find the backend element in the retrieve pipeline, and that's why it failed. We don't actually need any of the following lines: <retrieval syntax="xml" name="index" /> <retrieval syntax="xml" name="marc" identifier="info:srw/schema/1/marcxml-v1.1"/> <retrieval syntax="xml" name="marcxml" identifier="info:srw/schema/1/marcxml-v1.1"/> <retrieval syntax="xml" name="zebra::*" /> The only thing we need is <retrieval syntax="xml"/>. That provides access to the "marc", "marcxml", "zebra", and "index" backends defined in /etc/koha/zebradb/biblios/etc/dom-config.xml, as well as the zebra::* special retrieval elements. I've actually tested that on YAZ 5.1.2 and Zebra 2.0.60 on openSUSE, and it works great. I suppose the thing to do at this point is open a Bugzilla report to change "etc/zebradb/retrieval-info-bib-dom.xml", as well as "marc21-retrieval-info-bib-dom.xml", "normarc-retrieval-info-bib-dom.xml", and "unimarc-retrieval-info-bib-dom.xml". -- Installed Koha and Zebra on Debian Jessie using packages from scratch: sudo ls wget -O- http://debian.koha-community.org/koha/gpg.asc | sudo apt-key add - echo 'deb http://debian.koha-community.org/koha oldstable main' | sudo tee /etc/apt/sources.list.d/koha.list sudo apt-get update sudo apt-get install koha-common -- sudo apt-get install mysql-server <set mysql root password> <edit /etc/koha/koha-sites.conf : INTRAPORT="8080"> sudo a2enmod rewrite sudo a2enmod cgi sudo service apache2 restart echo 'deb http://ftp.indexdata.dk/debian jessie main' | sudo tee /etc/apt/sources.list.d/indexdata.list sudo apt-get update -- sudo apt-get install libidzebra-2.0 sudo koha-create --create-db libraryname sudo a2dissite 000-default.conf sudo vi /etc/apache2/ports.conf <add Listen 8080> sudo service apache2 restart sudo xmlstarlet sel -t -v 'yazgfs/config/user' /etc/koha/sites/libraryname/koha-conf.xml sudo xmlstarlet sel -t -v 'yazgfs/config/pass' /etc/koha/sites/libraryname/koha-conf.xml <choose MARC21 and all sample data> <create administrator patron> <create MARC record> <worth noting that it appears to use CHR indexing by default> yaz-client unix:/var/run/koha/libraryname/bibliosocket base biblios find test [109] Database unavailable -- v2 addinfo 'biblios' <wait a few seconds> base biblios find test Number of hits: 1, setno 3 show 1 <all good> format xml show 1 <all good> elements zebra::snippet show 1 [25] Specified element set name not valid for specified database -- v2 addinfo '' elements index show 1 <all good> elements marcxml ehow 1 <all good> elements marc <all good> -- elements zebra show 1 [biblios]Record type: XML <?xml version="1.0" encoding="UTF-8"?> <z:info xmlns:z="http://indexdata.com/zebra-2.0"; z:id="2" z:filename="/tmp/yIjODFCwAP/upd_biblio/exported_records" z:rank="0" z:score="" z:schema="zebra" z:size="938"/> -- sudo vi /etc/koha/marc21-retrieval-info-bib-dom.xml <remove "zebra::*" entry> sudo koha-restart-zebra libraryname Z> elements zebra::snippet Z> show 1 Sent presentRequest (1+1).
