I have a website with some pages like

* www.xyz.com/product1
* www.xyz.com/product2

and www.xyz.com/product1/***date*** which can be dynamic as what user searches.

Current google is indexing 

* www.xyz.com/product1
* www.xyz.com/product2
* www.xyz.com/product1/***date***

I dont want google to index www.xyz.com/product1/***date*** urls....
