[ckan-dev] recent Solr with space-separated, multi-valued fq parameter

[Philippe Duchesne]

Thank you for this pointer.
I understand solr 6 is the recommended version, but I had solr 7 has a
given constraint.

So, for the record, if solr 7 is ever to be supported, I managed to get the
whole thing running with the changes I mentioned, i.e. using fq_list
instead of fq whenever multiple filter values were required. That meant
patching ckan core, and ckanext-harvest.

best regards,

Philippe.
