Hi, We are having issues with a server we are building for a non-profit organization: to put it simply, the server works but no search result (on books or users) comes up and there is no error message (only "No result"). However, it is still possible to access a resource with the direct link or to list them all with "Home > Search the Catalog" (originally in french due to project constraints, translations will be approximated) and by doing an empty search. Moreover, the database seems to contain the entries. There is a lot of documentation online about this issue but none of the solutions worked out. An additional difficulty is that despite being a system administrator I have no prior knowledge in ILSs and the other persons on the project who work in libraries have no technical knowledge. Context: Server: OVH's VPS, Debian 9.6 Documentation used: [1] (links at the end of the mail) Koha: version 18.05 (and 17.11 tested as well) language setting: fr-FR format: unimarc ("unimarc-complet", no documentation on that specificity) Database: MariaDB 10.1.37 Search: Zebra (tried to switch to ElasticSearch, without success) Authority used: French National Library (Z39.50) Apache configuration: slightly tuned to fit technical constraints, intranet port moved to 8081 We originally tried the 18.05 but following an advice from someone working in a library with Koha we tried to test again with the 17.11, without success. Result of this answer [2]: <site>-koha@<server>:~$ export PERL5LIB=/usr/share/koha/lib <site>-koha@<server>:~$ export KOHA_CONF=/etc/koha/sites/<site>/koha-conf.xml <site>-koha@<server>:~$ /usr/share/koha/bin/migration_tools/rebuild_zebra.pl -b -r -v Zebra configuration information ------------------------- Zebra biblio directory = /var/lib/koha/<site>/biblios Zebra authorities directory = /var/lib/koha/<site>/authorities Koha directory = /usr/share/koha/intranet/cgi-bin Lockfile = /var/lock/koha/<site>/rebuild/rebuild..LCK BIBLIONUMBER in : 001$@ BIBLIOITEMNUMBER in : 090$a ------------------------- skipping authorities ------------------------- exporting biblio ------------------------- 1item-level_itypes set but no itemtype set for item (1) at /usr/share/koha/lib/Koha/Schema/Result/Item.pm line 698.

The zebra "indexer-output.log" file (and not error.log, strangely) contains exceptions that appear for each search: <site>-koha@<server>:~$ cat /var/log/koha/<site>/zebra-output.log 23:44:44-08/01 zebrasrv(1) [warn] ir_session (exception) 23:45:47-08/01 zebrasrv(2) [warn] ir_session (exception) 23:48:12-08/01 zebrasrv(3) [warn] ir_session (exception) 23:49:59-08/01 zebrasrv(4) [warn] ir_session (exception) 23:53:14-08/01 zebrasrv(5) [warn] ir_session (exception) 23:53:25-08/01 zebrasrv(6) [warn] ir_session (exception) 23:54:19-08/01 zebrasrv(7) [warn] ir_session (exception) 23:54:33-08/01 zebrasrv(8) [warn] ir_session (exception) 23:56:54-08/01 zebrasrv(9) [warn] ir_session (exception) 23:59:29-08/01 zebrasrv(10) [warn] ir_session (exception) 23:59:43-08/01 zebrasrv(11) [warn] ir_session (exception) 00:01:38-09/01 zebrasrv(12) [warn] ir_session (exception) 00:03:48-09/01 zebrasrv(13) [warn] ir_session (exception) 00:08:38-09/01 zebrasrv(14) [warn] ir_session (exception) 00:14:32-09/01 zebrasrv(15) [warn] ir_session (exception) 00:20:41-09/01 zebrasrv(16) [warn] ir_session (exception) 00:20:52-09/01 zebrasrv(17) [warn] ir_session (exception) 00:22:36-09/01 zebrasrv(18) [warn] ir_session (exception) 13:21:20-09/01 zebrasrv(19) [warn] ir_session (exception) 15:01:56-09/01 zebrasrv(20) [warn] ir_session (exception) 17:04:13-09/01 zebrasrv(21) [warn] ir_session (exception) But I have not found the origin The indexer-output.log is filled with SQL errors as well, <site>-koha@<server>:~$ cat /var/log/koha/<site>/indexer-output.log DBD::mysql::st execute failed: Table 'koha_<site>.zebraqueue' doesn't exist [for Statement "SELECT COUNT(*) FROM zebraqueue WHERE done = 0;"] at /usr/share/koha/bin/migration_tools/rebuild_zebra.pl [1] line 326.

It seems to be related to Zebra and/or the indexation, but the service was installed as provided without trailing out of the tutorials Thank you in advance for your help, Freely, [1] https://wiki.koha-community.org/wiki/Koha_on_Debian [2] https://koha-community.org/faqs/zebra-indexing-wont-work-fix-it-aka-search-s...
