 {{#ask:[[Category:User]]

Ask with OR connection 

{{#ask: [[Supervisor::{{SUBJECTPAGENAME}}]] OR [[Lecturer::{{SUBJECTPAGENAME}}]] OR 
[[User::{{SUBJECTPAGENAME}}]] OR [[{{SUBJECTPAGENAME}}]]

Ask for part of a string, e.g. all routers of type RDB52G - see example: RDB52G 

ask# [[Model::~*RDB52G*]]

ommit main label: | mainlabel=- |

Tips and Tricks, using Set

Recommendation from Neill: I always hide the raw page name as much as possible and use aliases so queries return more user friendly links.

{{#set:Page Link=[[{{FULLPAGENAME}}|{{{Page Title|}}}]]}} where Page Title is usually a field in the form. Sometimes I prepend with a section ID {{#set:Page Link=[[{{FULLPAGENAME}}|{{{Section ID|}}}-{{{Page Title|}}}]]}}

Then in the queries I return Page Link and use mainlabel=- to suppress the raw page name field.

{{#ask: |?Page Link .. .. |mainlabel=- }}

Note:

  • <section id="main"> <!-- main page content goes in here --> </section>
  • define Page Link as a Special:Property

Set syntax

set allows for properties linked to a page, e.g. Paris. Though can't be used for changing a property on a page, only adding more properties..., e.g. has postcode=7501|has postcode=7502|has postcode=7503. Note: not found out how to query one of them 

 {{#set:
 Has population=2,229,621
 |Located in country=France
 }}
