Lapteuh, Thanks very much for taking the time to report that issue, and give a corrected version-- we always appreciate that. The fix for this documentation error is already in the works, and should be out with the upcoming release. Btw, this slightly simpler syntax should also work: qry = Article.query().fetch(10, projection=[Article.author, Article.tags])
