Hi all! We just upgraded one of our clients to Elasticsearch and they happened to use the Did you mean feature. It seems Did you mean only works with Zebra. It's trying to connect to Zebra. This is in opac-error.log suggestion: oAuth error: Connect failed (10000) unix:/home/i/koha/alma-test-inlibro/var/run/zebradb/authoritysocket ZOOM: /inlibro/git/koha-alma-test-inlibro/opac/svc/suggestion, referer: http://alma-test.hapax.inlibro.net/cgi-bin/koha/opac-search.pl?q=chat (btw, "chat" is "cat" in french :D ) I think we should at the very least put a warning on the admin page for the Did you mean feature that it only works with Zebra. Otherwise make the feature engine agnostic so that we can use it with either Zebra or ElasticSearch. I don't know if Did you mean with elastic is necessary as there is a bz for autocomplete with ElasticSearch which does practically the same thing. (see bug 27113).
