Btw., another detail, if it searches but does not try, I think we should output a 
warning to the user.

Printing something like this would be more helpful:

   triton:~/tip> perf report -h --invert
 
     Search pattern '--invert' not found amongst the parameters. To resolve this 
     use a different search pattern or use '-h' to list all parameters.

Thanks,
