Although @Manuel Rony Gomes has answer the question, when you want to insert multiple documents found from collection A into collection B at once, you can use the toArray() to let it work:

db.coll_B.insert(db.coll_A.find({}).toArray())

use var doc1 = db.users.findOne({name:"Harmeet"})

db.users.find returns a cursor.
