Hi, For 2 years we've used Koha in a small community library in Alès, France; I'm not a professional librarian. Search did not work anymore with recently acquired items but it was OK for old ones; i updated koha from version 3.18.9 to version 3.18.10, but now the search doesn't work for any of the items. It doesn't work for a general search neither for a particular search (title, author, etc) The format of the database is unimarc. When i look at the zebrasrv logs it says zebrasrv(1) e0489cb5 [request] Search biblios ERROR 114 1 1+0 RPN @attrset Bib-1 @attr 1=1016 @attr 4=6 @attr 5=1 social I tried the yaz client directly, it says : # yaz-client -c /etc/koha/zebradb/ccl.properties unix:/var/run/koha/laretive/bibliosocket Connecting...OK.

Received SearchResponse. Search was a bloomin' failure. Number of hits: 0, setno 1 Result Set Status: none records returned: 0 Diagnostic message(s) from database: [114] Unsupported Use attribute -- v2 addinfo 'any' I did koha-rebuild-zebra but that didn't help (output is attached) I did the translation "perl translate install fr-FR" as well. Reinstalling koha 3.18.9 and reimporting the database doesn't help. A message in the mail archive related to this error [1] says that it could be related to the hidelostitems parameter, so i switched it but that didn't change anything. Another message in the archives [2] says that etc/zebradb/biblios/etc/dom-config.xml should be 54 lines long, and i found out that my etc/koha/zebradb/biblios/etc/dom-config.xml in only 48 lines long (but it's the file from the debian package so i guess it's correct). The file is attached. Any ideas ? [1] https://lists.katipo.co.nz/public/koha/2008-November/016048.html [2] https://lists.katipo.co.nz/public/koha/2014-June/039686.html
