What does 'separate' in sequelize mean? : <p>I searched in the official docs of sequelize and couldn't find any entry about '<code>separate</code>'.<a href="https://readthedocs.org/search/?q=separate" rel="noreferrer">https://readthedocs.org/search/?q=separate</a></p>

<p>I also searched on google but in vain.</p>

<pre><code>  db.fooTable.find({
        where: {
            id: id
        },
        include: [{
            model: db.barTable1,
            separate: true
        }, {
            model: db.barTable2,
            separate: true
        }, {
            model: db.barTable3,
            separate: true
        }]
    })
</code></pre>

<p>To find out what it means, I set '<code>separate</code>' to false, but the result of the query were the same as to when I put '<code>true</code>' instead.</p>
