Hello, On monday I make the upgrade on our linux server from Xwiki 5.1 to Xwiki 5.3. We are using Debian + POstgresql + Tomcat 7. The migration was OK, after the debian step I went to the admin migration tool inside Xwiki. I think I answer to all the conflict questions. And finally like said in the documentation I delete on the server the /var/lib/xwiki/data/solr directory. But something is not ok with solr. On the Admin page of "Recherche", on the SOlr research result page , on the top of the page I got this message : "#if ($searchEngine != $searchExtension.id) " At the bottom : " <label for="solrAdminAction">$services.localization.render('solr.admin.indexing.action.label')</label> <span class="xHint">$services.localization.render('solr.admin.indexing.action.hint')</span> " It sounds like some translations are not there. But the real problem is there the research is very limited. I ask Solr to recreate all indexes, reboot the server after a will, but nothing change. I know some very used words in our organisation, in pages or inside attached documents, but Solr show a few of them. Any idea ? Thanks Cordialement Stéphane Lassire
