  1. Hello Chris, Thanks for the stat. I disagree with this sentence (unfortunately): “Koha in 3.10.0 works with either Zebra or Solr” which is a shortcurt. Koha is know able to switch between search engines but there is a looooot of work to do (zebra refactoring and after only introducing more solr devs) to have more than a poc (or maybe I musunderstand with either xx or yy”).


    1. Well it works fine with Zebra, and you can make it work with Solr by switching the sysprefs. Authorities aren’t yet working with Solr, but a basic search works. Zebra is still the most feature rich in 3.10.0 though you are right.
