Hello guys! I`m need create index Product collection, wich has  
the following structure:

{  
"\_id": ObjectId("5239656f60663de206b1053e"),  
"category": {  
"$ref": "Category",  
"$id": ObjectId("50cb515760663d3577000043"),  
"$db": ""  
},  
"name": ""  
}  
Field 'category' is link to another row from Category collection, I need  
create an index, which would have the following structure:  
{  
"\_id": "",  
"name": "",  
"category": ""  
}  
That is i get productName from Product collection and categoryName from  
Category collection. Any idea?
