Hi Ndaona

Yes Zebra is started, it was working perfectly but from last two weeks it just stopped and searching the catalogue from the staff client is not working, the same problem occurred last month and we tried to rebuild it to no avail up to the extent we just installed a fresh koha and zebra was working until last two weeks when the same problem has occurred. We have been using koha version 3.5 since 2015 and this problem never happened and now we upgraded to koha version 20.05 running in ubuntu 20.04 and we are being hit by the same problem of zebra showing "No results found-No results match your search for 'kw,wrdl: clinical medicine'" Please help.

If I understand correctly, you are running Koha 20.05 on Ubuntu 20.04. As far as I know Koha 20.05 is officially only supported for Ubuntu 18.04: * Debian 8 (Jessie) with MySQL 5.5 (End of life) * Debian 9 (Stretch) with MariaDB 10.1 * Debian 10 (Buster) with MariaDB 10.3 * Ubuntu 18.04 (Bionic) with MariaDB 10.1 * Debian 9 (Stretch) with MySQL 8.0 (Experimental MySQL 8.0 support) See https://koha-community.org/koha-20-05-released/ However, I would do the following: 1. Check if Zebra is really running - otherwise you won't find anything in your catalog. The following command $ ps -ef | grep zebra should show some processes like the following: hfs-koha 796 1 0 Apr15 ? 00:00:00 daemon --name=hfs-koha-zebra --pidfiles=/var/run/koha/hfs/ --errlog=/var/log/koha/hfs/zebra-error.log --output=/var/log/koha/hfs/zebra-output.log --verbose=1 --respawn --delay=30 --user=hfs-koha.hfs-koha -- /bin/zebrasrv -v none,fatal,warn -k 1024 -f /etc/koha/sites/hfs/koha-conf.xml hfs-koha 797 796 0 Apr15 ? 00:00:00 /bin/zebrasrv -v none,fatal,warn -k 1024 -f /etc/koha/sites/hfs/koha-conf.xml hfs-koha 1068 1 0 Apr15 ? 00:00:00 daemon --name=hfs-koha-indexer --errlog=/var/log/koha/hfs/indexer-error.log --stdout=/var/log/koha/hfs/indexer.log --output=/var/log/koha/hfs/indexer-output.log --pidfiles=/var/run/koha/hfs/ --verbose=1 --respawn --delay=30 --user=hfs-koha.hfs-koha -- /usr/share/koha/bin/migration_tools/rebuild_zebra.pl -daemon -sleep 5 hfs-koha 1069 1068 0 Apr15 ? 00:01:47 /usr/bin/perl /usr/share/koha/bin/migration_tools/rebuild_zebra.pl -daemon -sleep 5 2. If Zebra is not running, start it using the following command: $ sudo koha-start-zebra After you have started Zebra, as above, check if it is really running with $ ps -ef | grep zebra 3. If you can't start Zebra check your log files: $ cd /var/log/koha/<instance> $ more zebra-error.log There are also other log files in this directory that may give you a hint. Hope this helps.

Hi Lyson

Is there any way we can rebuild zebra in koha apart from running "sudo koha-rebuild-zebra -v --full $(/usr/sbin/koha-list)" It stopped working two weeks ago and trying this command won't solve the problem. We are unable to search the catalogue from the staff client and OPAC.

Are you sure if your Zebra is started?

If not then start it with

$ sudo koha-start-zebra <instance>

In case of trouble please always mention the version of your operating system and the version of your Koha as an absolute minimum.

Hope this helps.
