Descending sort '-_id' is not working [mongodb 2.6.11]

[yousaf-harry]

I came across a strange issue; sorting on id field with '-' is not working and does not return anything where as without '-' is working fine.

This does not work query_set.order_by('-_id')
where as this is working query_set.order_by('_id')

I have monogdb 2.6.7 on my local machine and both of the above conditions work there. Where as on my CentOS server I have mongodb 2.6.11 and it fails on it.

Probably that issue related to mongodb version. I can not reproduce it with v3.2.3

You can check mongodb query log and compare executed db.find(..) commands.
