Description
The indexOnly flag is currently always false for projections including sub-documents:
>db.test.insert({x:1,p: {s:1}})
|
>db.test.ensureIndex({x:1,'p.s':1})
|
>db.test.find({x:1},{x:1,'p.s':1,_id:0}).explain().indexOnly
|
false
|
no different query projection seems to enable indexOnly : true on sub documents.
