Redirecting bad external URL with ? parameters

[Mister Denial]

Hello,

 

G Webmaster Tools shows me some duplicate content warning for three URLs, all of which are completely wrong, yet open the home index page of our shop. The URLs looks like this:

 

/?P2403_Quantity=1&P2405_Quantity=1&P2452_Quantity=1&P2458_Quantity=1&P2755_Quantity=1&P2400_Quantity=1&P2412_Quantity=1&P2404_Quantity=1&P2759_Quantity=1&P2761_Quantity=1&P1624_Quantity=1&P2753_Quantity=1

/?P2814_Quantity=1&P2367_Quantity=1&P2830_Quantity=1&P2374_Quantity=1&P1565_Quantity=1&P1560_Quantity=1&P1566_Quantity=1&P1542_Quantity=1&P1553_Quantity=1&P1100_Quantity=1

/?lang=en-us&idx=0&id=6091213

 

I could not get rid of these with a classic 410 redirect, nor can I get the 301 to work. Can someone help me please?

 

Thank you!

Does anyone know if it is possible to write a rule to redirect there bads URLs to the main page? A 301 redirect maybe?
