The test page on the semantic mediawiki demo site has a "Sort options" box: https://www.semantic-mediawiki.org/wiki/Special:Ask
But my site with up-to-date semantic mediawiki installed does not: http://wiki.andelainfilms.com/index.php/Special:Ask
This is consistent with behaviour when adding sort properties to tables, nothing makes any influence on the order of results despite documentation to the contrary.
Am I missing an extension that makes this happen?
