Creating Partitioned Tables and Indexes
http://technet.microsoft.com/en-us/library/ms187526(v=sql.105).aspx
you can create a aligned index, the index will be spread over the filegroups
Create NonClustered Index IX_orders_aligned
On dbo.orders(order_id)
On test_monthlyDateRange_ps(orderDate);
OR
Unaligned parition, you can create index on any filegroups
Create NonClustered Index IX_orders_unpartitioned
On dbo.orders(order_id)
On [Test_prt2_FileGroup];

Or
You can try Creating a filtered index (I've not tried it though)
