[edit] Subquery example

For a question about cities in the European Union we could either enumerate the countries of the European Union by hand, or use nested queries like this, and thus avoid the need to update the query in case the EU admits a new member:

<ask sort="located in" limit="10" link="all">
  [[Population:=>30000]]
  [[Category:Cities]]
  [[located in::<q>[[Category:Country]] [[member of::European Union]]</q>]]
  [[located in::*]] [[Population:=*]] 
</ask>
