  • Doesn't return a valid result because the value is matched against the smw_title field which is not made NOCASE to distinguish between entities like (some vs. Some)
  • Page types (_wpg) are resources that can be linked and referenced therefore matching a distinct entity is required, meaning to match exactly [[Page::some title with a value]]

  • ~ as match operator is to direct the search towards the smw_sortkey field (a field that is made NOCASE)
  • In case the full-text index is enabled then the search is redirected to the full-text index given that the SMW_FT_WIKIPAGE option is enabled as well

  • like: match operator is to direct the search towards the smw_sortkey field which is made NOCASE and independent whether the full-text index is enabled or not

  • A text or string is a simple value no resource as in case of a page value therefore is treated with more leniency
  • A standard search will match against any possible NOCASE as well since blob fields are made case insensitive
{{#ask:
 [[Category:2499]]
 [[Text::~some title with a value]]
 |?Text
 |format=ul
}}
  • ~ operator matches the full-text index, if full-text search is enabled otherwise uses the standard blob field
{{#ask:
 [[Category:2499]]
 [[Text::like:some title with a value]]
 |?Text
 |format=ul
}}
  • like: operator matches the standard blob field independent whether the full-text index is enabled or not

URL[modifier | modifier le wikicode]

In case of the SMWElasticStore, the $smwgElasticsearchConfig['query']['uri.field.case.insensitive'] = true; configuration setting is required to make the listed function to use a case insensitive context.
