Quirks with Solr6

[TkTech]

Some quirks with CKAN and up-to-date versions of Solr:

• default field in the schema is deprecated: [ckan] default search field in schema is text. WARNING: Deprecated,​ please use 'df' on request instead.
• When multiple terms are provided (like an org filter) the field name to search must be explicit. This is currently breaking searching for terms within an organization (q=test +owner_org:... fails, q=text:test +owner_org:... works, q=test works).
• While we're here, owner org should be a filter not part of the query.

For point 2, a very small change should be forward and backwards compatible and safe for back-porting. Ex:

diff --git a/ckan/controllers/group.py b/ckan/controllers/group.py
index 087209f..912c402 100644
--- a/ckan/controllers/group.py

@@ -236,6 +236,9 @@ class GroupController(base.BaseController):
                    'for_view': True, 'extras_as_string': True}

         q = c.q = request.params.get('q', '')
+        if q is not None and q.strip():
+            q = 'text:{q}'.format(q=q)
+
         # Search within group
         if c.group_dict.get('is_organization'):
             q += ' owner_org:"%s"' % c.group_dict.get('id')

Is solR 6.0.0 supported with CKAN 2.7.2 ?

I'm getting this error:

I read in stack overflow to downgrade the solR to v5.0.0.
