Thank you for the answers and now "cut after" option is on again.
We have the cut after ? and then it comes crap and then after that a = and after that the parameter that we want to filter on comes.
Normally parameters will show up like http://something.com/page.html?parametername=Para...
With the "cut after ?" you will only get http://something.com/page.html as a operation name.
If you want to get the parameter as well you will switch to the "Dimensions, Metrics and Attributes" (hope I got it correct) tap in the Software Service and define a rule for a miscalleanous parameter. This can be by "searching for parametername" or "searching for parametername and value", after defining this the URI should show up as http://something.com/page.html?parametername=Parametervalue
again (depending a little bit what you defined in the miscalleanous parameter).
