You can pass more than one value in a single parameter. For the example above use "OR" between the two cities, such as:
http://www.yourdomain.com/mypage.htm?city=Chicago OR Detroit
Set your filtering field’s Comparison type to ‘Contains’ and set it to receive the value of parameter [@City].
Note: This solution can be used only for text fields.
