The find
function in mongoose is a full query to mongoDB. This means you can use the handy mongoDB $in
clause, which works just like the SQL version of the same.
model.find({
'_id': { $in: [
mongoose.Types.ObjectId('4ed3ede8844f0f351100000c'),
mongoose.Types.ObjectId('4ed3f117a844e0471100000d'),
mongoose.Types.ObjectId('4ed3f18132f50c491100000e')
]}
}, function(err, docs){
console.log(docs);
});
This method will work well even for arrays containing tens of thousands of ids. (See Efficiently determine the owner of a record)
I would recommend that anybody working with mongoDB
read through the Advanced Queries section of the excellent Official mongoDB Docs
