The search template special:search allows you to include a list of pages that include a certain template or set a defined value within a template.
This template is especially useful for index and category pages.
Note: due to "aggressive" caching, your browser may not show a complete list of all pages. If you want to make sure, then force a hard reload (shift+reload or ctrl+reload depending on browser). But usually, this should not be a problem.
The template understands following parameters:
We define the example template in 'hidden mode' here, with name=Dieter.
{{special:search | template=HowTemplatesWork/Example }}
yields
No matching pages found.
{{special:search | parameter=HowTemplatesWork/Example:name }}
yields
No matching pages found.
{{special:search | parameter=HowTemplatesWork/Example:name | value=Dieter }}
yields
No matching pages found.
