Thiemo_WMDE, hi and thanks... I may have asked this question before the Tech Advice meeting began so forgive me for posting it a 2nd time.. the question is:

I have a template that implements a property that holds an list of values. 
For example:
{{MyTemplate
|has Users=User:Tom, User:Jane, User:Mike
}}
I'm trying to write an #ASK statement in another page that finds all pages where "User:Jane" is NOT one of the values of "has Users" .. the following SMW ASK statement does not work:
{{#ask:
[[has Users::!*User:Jane*]]
}}
can someone help me determine how to I write an ask statement that successfully involves selecting pages where a property value does not contain the string <some string>"?

Thanks!
