Hello koha-devel, A big thanks to Hugo Agud and the Orex Spanish company for their sponsoring of BibLibre work on Elastic Search. We used this sponsoring to investigate ES 6.0 support. Alex already wrote a patch that has to be signed-off : https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=18969 PS: Hugo, (as many others) will be at the hackfest and we will have fun with Koha & ES !!! -- Paul Poulain, Associé-gérant / co-owner BibLibre, Services en logiciels libres pour les bibliothèques BibLibre, Open Source software and services for libraries
