$smwgQSortFeatures is a configuration parameter that sets behaviour for the sorting features of the semantic search. The configuration parameter was introduced in Semantic MediaWiki 3.0.0Released on 11 October 2018 and compatible with MW 1.27.0 - 1.31.x.1 and deprecated the configuration parameters as indicated in the section on available options below.

The deprecated configuration settings as indicated in the section on available options should be migrated to this configuration setting in "LocalSettings.php" since they will be removed with the release of Semantic MediaWiki 3.1.0Released on 23 September 2019 and compatible with MW 1.31.0 - 1.33.x. in 2019.1

Default setting

$smwgQSortFeatures = SMW_QSORT | SMW_QSORT_RANDOM;

This means that the two respective features, as explained in the following sections on available options, are enabled.

Available options

The options enabled by default are highlighted bold.

• SMW_QSORT_NONE – Disables sorting features of the semantic search
• SMW_QSORT – Sets that sorting of query results is possible

  Note: This option replaces configuration parameter $smwgQSortingSupportSets whether sorting of query results should be possible.

• SMW_QSORT_RANDOM – Sets that random sorting of query results is possible

  Note: This option replaces configuration parameter $smwgQRandSortingSupportSets whether random sorting of query results should be possible.

• SMW_QSORT_UNCONDITIONAL – Sets that sorting by a property will work unconditionally even if the respective property was not set to all pages selected, i.e. all pages will be shown2

  Note: This option is currently considered experimental and not available to SPARQLStore stores and SMWElasticStore store.

For further information on the available options listed above see the documentation pages of the respective deprecated configuration parameters as stated above.

Changing the default setting

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

Removing a specific query sorting feature

To disable a specific feature e.g. random sorting of query results just redefine the configuration parameter by defining it without the corresponding constant as shown in the above section on available options:

$smwgQSortFeatures = SMW_QSORT;

or alternatively remove the option from the existing definition of the configuration parameter like e.g.

$smwgQSortFeatures = ( $smwgQSortFeatures & ~SMW_QSORT_RANDOM );

  Note: Please use parentheses3 when combining different bit-operations to avoid a possible mismatch.

Adding a specific query sorting feature

To add a specific feature e.g. unconditional sorting of query results just redefine the configuration parameter by defining it including the corresponding constant as shown in the above section on available options:

$smwgQSortFeatures = $smwgQSortFeatures | SMW_QSORT_UNCONDITIONAL;

Disabling all query sorting features

To disable all browse features just remove all constants as shown in the above section on available options:

$smwgQSortFeatures = '';

or add the constant for disabling all query sorting features

$smwgQSortFeatures = SMW_QSORT_NONE;
