node.js - Partial indexes in mongodb / mongoose

In the sparse index documentation I found note about mongodb 3.2 partial indexes

Changed in version 3.2: Starting in MongoDB 3.2, MongoDB provides the option to create partial indexes. Partial indexes offer a superset of the functionality of sparse indexes. If you are using MongoDB 3.2 or later, partial indexes should be preferred over sparse indexes.

Partial indexes are very helpfull and I want to use them in my project. Is it possible use them with mongoose?

Now it's possible natively with Mongoose +4.6.1

Book.index({user: 1, author: 1, complete: 1}, {unique: true, partialFilterExpression: {complete: true}});
