List objects with a certain id in MongoDB regardless of collection

search_id.js

var searchId = function (objId) {
 coll = db.getCollectionNames();
 coll.forEach(function(collName) {
   obj = db[collName].findOne({'_id': ObjectId(objId)});
   if (obj !== null) {
     print(collName + " " + objId);
     
   }
 });
};
