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

[Philippe Duchesne]

Hello,

I currently have to deploy a CKAN 2.7 instance with Solr 7.3 .
It turns out that most dataset search requests fail, in that they return
all records.

After some debugging, it appears that this instance of Solr does not
process properly fq values that contain space-separated filters, as those
produced by search/query.py, like
'organization:"acme" +dataset_type:dataset -dataset_type:harvest
+site_id:"mysite" +state:active'

I can't find any record of this in ckan or solr issues. Is this a known
problem, or a misconfiguration on my part?
I have a PR I can submit that replaces all space-separated fq values with
fq_list usage, but i'd like to know if this is a relevant fix first.

Thanks,

--p.
