$smwgQComparators is a configuration parameter that sets the list of comparator characters supported by queries for use in a regex. The parameter was introduced in Semantic MediaWiki 1.0.

If unsupported comparators are used, they are treated as part of the queried value. The behaviour of the comparators < and > varies depending on the setting for $smwStrictComparators.

Default setting

$GLOBALS['smwgQComparators'] = <|>|!~|!|~|||<<|>>;

The default setting allows all available comparators.

Changing the default setting

The available features are combined in a list, separated by a pipe "|". Example:

do not allow extended ASCII character comparators
$smwgQComparators = <|>|!~|!|~|<<|>>;

NoteNote:  This cannot be combined with strict comparators enabled.

Available comparators

  • < (smaller than or equal)
  • > (greater than or equal)
  • << (smaller than)
  • >> (greater than)
  • (smaller than or equal - note that this is an extended ASCII character and may show up differently, e.g. as "â¤")
  • (greater than or equal - note that this also is an extended ASCII character and may show up like "â¥")
  • ! (unequal to)
  • ~ (matching a pattern with "*" as wildcard, only for datatype "Text" and "Page")
  • !~ (not matching a pattern with "*" as wildcard, only for datatype "Text" and "Page")
