在Angularjs应用程序中，使用嵌套对象属性过滤ng repeat不起作用

我有以下json，

$scope.accountsList = [    {
      "id": 1,
      "number": "AFRC1234",
      "name": "ACFRYTE431", 
      "postalCode": "76565",
      "invoices": null,
      "courier": {
        "id": 1,
        "name": "UPS"
      },
      "client": {
        "id": 1,
        "code": "FREG",
        "name": "Feranget"
      }
    } ]

我正在将ng-repeat过滤为

<tr ng-repeat="account in accountsList | filter:{ number: accountSearch.accountNumber,  name: accountSearch.accountName, client.name : accountSearch.clientName}">

在我的控制器中，我有：

 $scope.accountSearch = {
                accountNumber :'',
                accountName : '',
                clientName : ''
        };

如果我删除client.name : accountSearch.clientName，在ng个重复过滤标准中，accountsList是基于accountNumber和accountName正确过滤的。但是，当我将client.name : accountSearch.clientName包含在ng重复筛选条件中时，控制台中会显示以下错误，并且不会进行accountsList的筛选。

Error: [$parse:syntax] Syntax Error: Token '.' is unexpected, expecting [:] at column 66 of the expression [accounts | filter:{ number: accountSearch.accountNumber,   client.name : accountSearch.clientName }] starting at [.name : accountSearch.clientName }].

有人能帮忙修理吗？
