update only few documents

[David Lavy]

I am trying to update only 5 first documents and cant find any solution.

the best solution i could find is 

db.collection.find(<condition>).limit(<limit>).forEach(function(doc){db.collection.update({_id:doc._id},{<your update>})})

but this is not good enough for me. I need to update the 5 in bulk immediately and not separate.

Thank you

You can't.

Update allows you to update the first match (default) or multi which allows bulk update. 

If there is no way for you to create a criteria that only brings back the exact 5 then I would opt for the streaming API.
