如何检索3天的文档？

Question

如何检索3天前的所有文件（从发布之日起）？

与SQL中给出的类似的东西： Checking if date is more than 3 years old in PostgreSQL

SELECT * FROM foos WHERE date < '3 days'::interval;

Answer 1

db.collection.find({created_at : {$gt : <fill in the date of the day before three days back  in the right format> })

应该有效
