If I have correctly understood, you need using $or inside of $and function in Mongodb or mongoose, both of them supports these two functions. For example (in mongoose):

cModel.find(
        {
            $and: [
                {
                    $or: [
                        { name: { $regex: new RegExp(`^${company.name}$`, 'i') } },
                        { company_code: { $regex: new RegExp(`^${company.company_code}$`, 'i') } }
                    ]
                },
                {
                    is_delete: true
                }
            ]
        }, function (err, docs) { 
            if(docs){
                // throw error!
            } if (!docs) {
                // enter your new doc here with cModel.create(yourDoc, function(error, data){});
            }
        }
    );
