Sort order in drilldown results
Is it possible to order the results by their frequency? --Dusanson 17:17, 28 January 2012 (UTC)


 * Hi - unfortunately, no. Yaron Koren 14:41, 29 January 2012 (UTC)

has drilldown title property not working
I am unable to get the "has drilldown title" property working. I set it in my category here: http://thisishowyouplay.com/wiki/Special:Browse/Category:Activities

but when I try to browse data, it still says "browse data" on this page: http://thisishowyouplay.com/wiki/Special:BrowseData/Activities?_single

thanks again. Chrisisready 02:27, 12 February 2012 (UTC)


 * Yes - you've discovered a problem that seems to occur with more recent versions of MediaWiki - starting with MW 1.18 or 1.18.1. I think I just fixed it in SVN - see here. Yaron Koren 16:10, 12 February 2012 (UTC)
 * Thanks Yaron! The patch worked great. You're the best. Chrisisready 19:09, 12 February 2012 (UTC)

After the upgrade from 1.17.x to 1.18.1 the DrillDown gave up working
My configuration: and
 * MediaWiki	1.18.1
 * PHP	5.2.17 (cgi)
 * MySQL	5.0.91mm-log
 * Semantic Bundle (Version 20120124)
 * Semantic Forms (Version 2.3.2)
 * Semantic MediaWiki (Version 1.7.0.2)

http://tunearch.org/Special:BrowseData now shows just a list of articles in category, in alphabetical order. Are there configuration issues related to the semantic bundle that I'm missing?

I have entered the following in my LocalSettings.php $sdgNamespaceIndex = 170; require_once( "$IP/extensions/semantic-bundle/SemanticBundleSettings.php" ); require_once( "$IP/extensions/semantic-bundle/SemanticBundle.php" );
 * 1) THE SEMANTIC BUNDLE  ######

and this in the $IP/extensions/SemanticBundleSettings.php include_once( "$IP/extensions/SemanticDrilldown/SemanticDrilldown.php" ); $sdgShowCategoriesAsTabs = false; $sdgFiltersSmallestFontSize=9; $sdgFiltersLargestFontSize=25; $sdgNumResultsColumns=1; $sdgNumResultsPerPage=250;
 * 1) Semantic Drilldown
 * 2) More info: http://www.mediawiki.org/wiki/Extension:Semantic_Drilldown#Installation

I also run the $IP/extensions/SemanticMediaWiki/maintenance/SMW_refreshData.php more than once... nothing happened. Please help! VALERIO M. PELLICCIONI - 18:46, 12 February 2012 (GMT+1)


 * Hi - it looks like you got both the URL and the date wrong... anyway, this looks like the page you're talking about, and the filters seem to be working correctly there. Is there still a problem? Yaron Koren (talk) 19:30, 9 March 2012 (UTC)

Slow to load page links on Semantic Drilldown
UPDATE!!!!: The problem seems to only exist in Chrome. Are there any known incompatibilities or conflicts with Chrome?

Hello -- I have several filters set up and on one of them, there are serious performance issues. The links to pages that meet the criteria load immediately, but it takes 10 seconds until they can be clicked on. On some filters, things work fine but on the one with perhaps several hundred values, it is very laggy. What is a reasonable number of values a filter can have before performance suffers?

I know that one option is to have a restricted set of values and to use a Combo Box. However, I'd greatly prefer not to do that since I want to allow users to add their own tags.

Are there any recommended speed enhancements specifically for using Semantic DrillDown?

I tried the following speed enhancements to no avail:
 * $smwgQEnabled=false;
 * $smwgQEqualitySupport=SMW_EQ_NONE;

I'm not sure if caching has been setup yet... would that improve the issue? I'm not very experienced and would prefer to avoid setting up PHP caching unless that would definitely fix the problem.

I am running:
 * Semantic Drilldown .0.8.3
 * Semantic Mediawiki 1.5.5 alpha
 * Mediawiki 1.17.0
 * PHP 5.3.3 (apache2handler)
 * MySQL 5.1.61

Thanks in advance for any help. SEE UPDATE ABOVE!!!!


 * Hi - the choice of browser really shouldn't have any effect, since all the performance-intensive stuff done by Semantic Drilldown is server-side. Also, SMW settings should have no effect (as you discovered), since SD does direct SQL queries, instead of going through SMW. You could try upgrading SD (and SMW) - I don't know if that will have an effect, but it couldn't hurt, and it's a good idea anyway. If that doesn't help, it could be that switching to combo boxes is the best solution, for now. Yaron Koren (talk) 02:29, 8 April 2012 (UTC)

Excluding a page from drilldown
Is there a way to exclude particular page from showing up within drilldown? Something like __HIDEFROMDRILLDOWN__ for pages? --Dusanson (talk) 13:49, 25 April 2012 (UTC)
