MongoDB: Only fetch documents created in the last 24hrs?

Question

I want to limit a query I\'m making to only look in documents that were created in the past 24 hrs.

What is the best way to structure this query? How do I go about

Answer 1

Add createdAt field, index it, then query

db.getCollection("COLLECTION_NAME").find({"createdAt":{$gt:new Date(Date.now() - 24*60*60 * 1000)}})

This will return all records older then 86400 seconds.
