ngRepeat Filter by deep property

If I have a complex object with objects as property values, how can I filter by one of the nested properties?

Can this be done with the OOB ng-repeat filter?

Data

{
  Name: 'John Smith',
  Manager: {
     id: 123,
     Name: 'Bill Lumburg'
  }
}

ngRepeat

<li ng-repeat="e in emps | filter:Manager.Name">{{ e.Name }}</li>

You need to pass in the argument to filter by:

<input ng-model="filter.key">
<ul>
  <li ng-repeat="e in list | filter: {Manager: {Name: filter.key}}">
    {{e.Name}}  (Manager: {{e.Manager.Name}})
  </li>
</ul>

Example on Plunker

If you are filtering multiple properties then the syntax would be similar to below.

<ul>
  <li ng-repeat="item in list | {filter: top_object_property_name: value, top_object_property_with_nested_objects_name: {nested_object_property_name: value}}">
       ...
  </li>
</ul>

eg:

        var employees = [name: 'John', roles: [{roleName: 'Manager'},{roleName: 'Supervisor'}]];
        
        <li ng-repeat="staff in employees | {filter: name: 'John', roles: {roleName: 'Manager'}}">
              ...
        </li>

In latest version of angularjs nested obj filter implemented by default.can use filter normally. It for angular 1 only

To filter with multiple deep property we need to create custom filter. What i mean we need to create our own function to filter the data in object and return the required object(filtered object).

For example i need to filter data from below object -

[{   "document":{      "documentid":"1",      "documenttitle":"test 1",      "documentdescription":"abcdef"       }},{   "document":{      "documentid":"2",      "documenttitle":"dfjhkjhf",      "documentdescription":"dfhjshfjdhsj"       }}]

In HTML we use ng-repeat to show document list -

<div>
   //search input textbox
   <input ng-model="searchDocument" placeholder="Search">
 </div>
<div ng-repeat="document in documentList | filter: filteredDocument">
   //our html code 
</div>

In Controller we write filter function to return filtered object by using two properties of object which are "documenttitle" and "documentdescription", code example is as below -

function filterDocuments(document)
        {
            if($scope.searchDocument)
            {
                     if(document.documentTitle.toLowerCase().indexOf($scope.searchDocument.toLowerCase()) !== -1 || document.document.shortDescription.toLowerCase().indexOf($scope.searchDocument.toLowerCase()) !== -1)
                {
                    //returns filtered object
                    return document
                }
            }else {
               return document;
            }
        }

Where $scope.searchDocument is the scope variable which binded to the search textbox (HTML input tag) in which user can input the text to search.
