This solved the problem for my WordPress based blog. You may have to wait one year before the supplemental results are gone. Google is slow with cleaning the supplemental index.
"there are like 20 results for www.example.com/?q=Hotel+Suites+Weddings and stuff like that.The worst part is that they actually go to the index page of the blog, is there actually any way to remove those results? "
If someone knows the answer to this, let me know! I have almost the very same problem.
