$smwgQEqualitySupport is a configuration parameter that sets whether redirects between page names are considered as equality between the described objects. This is usually appropriate for cases where data is given for a page at all. The configuration parameter was introduced in Semantic MediaWiki 1.0Released on 31 December 2007 and compatible with MW 1.9.x - 1.12.x..

Starting with Semantic MediaWiki 7.0.0Released on 4 June 2026 and compatible with MW 1.43.x - 1.46.x. this parameter accepts a plain string value instead of the SMW_EQ_* constants. The constant form still works but is deprecated and will be removed in Semantic MediaWiki 8.0.0Released on an unknown date and compatible with unknown versions of MediaWiki..1

Default setting

$smwgQEqualitySupport = 'some';

This means that redirects are evaluated as equality between page names, with possible performance-relevant restrictions depending on the storage engine.

Available options

The option enabled by default is highlighted in bold.

• 'some' (formerly SMW_EQ_SOME) – Evaluate redirects as equality between page names, with possible performance-relevant restrictions depending on the storage engine
• 'full' (formerly SMW_EQ_FULL) – Evaluate redirects as equality between page names in all cases
• 'none' (formerly SMW_EQ_NONE) – Never evaluate redirects as equality between page names

Changing the default setting

To modify the setting to this configuration parameter, add one of the following lines to your "LocalSettings.php" file:

Never evaluate redirects as equality

$smwgQEqualitySupport = 'none';

Evaluate redirects as equality in all cases

$smwgQEqualitySupport = 'full';

Changing this option may only take effect after recreating all data in the database. See Repairing SMW for details.
