Mongo节点js查询隐式$and

Question

It should only update and return results that have match on the request data.

it should be not mutually exclusive (ie if one query does not match then do not return result results)

is using implicit $and a solution to that ?

Query

  keystone.list('Vehicle').model.update({ $or: [{ Body: { $in: req.body.data[0].body } }, { Model: { $in: req.body.data[0].model } }, { Make: { $in: req.body.data[0].make } }, { Year: { $in: req.body.data[0].year } }] }, {
                    $set: {
                        'Summer_Sale_Event': req.body.summer_sale_value
                    }
                }, {
                    'multi': true
                }).exec(function (err, result) {

                });

Request data

Request : [ { body: [ 'Convertible' ],
    make: [ 'Chevrolet' ],
    year: [ '2005' ],
    model: [ 'Corvette' ] } ]

Answer 1

$or means that only one of the condition have to be true. You should be using $and instead.
