Where clause for associated objects with Node and sequelize - node.js

Question

I have Books which have an author and an editor. I'd like to query for all books with a title like '%gone% and author.name like '%paul%' - I couldn't find documentation about doing this, but I've tried various formats based on what I've googled.
Attempt using a filter on includes:
var includes = [
{"model": db.User, as: 'Author', through: {"where": {"name": { like: '%paul%'}}}}
];
var filter = { title: { like: '%gone%'}};
return Book.findAll({ include: includes, order: 'id desc', where: filter});
While the restriction on title works, the author name is ignored (no errors).
Variation without the 'through' (same result - doesn't affect resultset):
var includes = [
{"model": db.User, as: 'Author', "where": {"name": { like: '%paul%' } } }
];
And how I initiatively thought it might work (causes error):
var filter = { title: { like: '%gone%'}, 'author.name' : { like : '%paul%' } };
Any clues or pointers to documentation to help me do this??
Thanks.
Model:
var User = sequelize.define('User', {
name: {
type: DataTypes.STRING
},
...
classMethods: {
associate: function (models) {
User.hasMany(Book, { as: 'Author', foreignKey: 'author_id' });
User.hasMany(Book, { as: 'Editor', foreignKey: 'editor_id' });
},
...
}
var Book = sequelize.define('Book', {
title: {
type: DataTypes.STRING,
len: [20]
},
...
classMethods: {
associate: function (models) {
Book.belongsTo(User, { as: 'Author', foreignKey: 'author_id' });
Book.belongsTo(User, { as: 'Editor', foreignKey: 'editor_id' });
},
...

I got it to work by removing the 'as' in the User associations to Book to:
User.hasMany(Book, { foreignKey: 'author_id' });
User.hasMany(Book, { foreignKey: 'editor_id' });
Then I can filter as expected with:
var includes = [
{model: db.User, as: 'Author'},
{model: db.User, as: 'Editor'}
];
var filter = { title: { like: '%gone%'}, 'Author.name' : { like : '%paul%' } };
return Book.findAll({ include: includes, order: 'id desc', where: filter});
It helped to turn on logging of SQL statements as described here: How can I see the SQL generated by Sequelize.js?
