I have an aggregate function like this
app.get('/feed', (req, res) => {
TFBlog.aggregate([
{ $sample: {size: 5} },
{ $match: {"published": true} },
]).then((docs)=>{
res.render('explore',{docs:docs});
});
});Now if aggregate finds a document that doesn't satisfy {published: true} it simply returns an empty array
So in many Use cases, I get 4 or 3 documents in return array instead of 5
I want this function to always return 5 random documents with $match criteria no matter what!!
How can I achieve this please explain?
Move $match condition to the top ?
db.collection.aggregate([
{ $match: {"published": true} },
{ $sample: {size: 5} }
])
