Filtering nested objects in ng-repeat with a search input field

Solution

I've finally got the answer to my own question.

I only had to create my own filter and check if the properties inside the object have the desired value by using regular expressions:

app.filter('customSearchFilter', function() {
return function(input, term) {
    var regex = new RegExp(term || '', 'i');
    var obj = {};
    angular.forEach(input, function(v, i){
      if(regex.test(v.name + '')){
        obj[i]=v;
      }
    });
    return obj;
  };
});

And apply it in the HTML this way:

<input type="text" ng-model="searchName" />
<ul>      
  <li ng-repeat="(key, val) in items | customSearchFilter:searchName">Both {{key}} and {{val.name}}</li>
</ul>

Problem

I am trying to filter nested objects in ng-repeat by using a search textbox. Given the following object: ``` $scope.items = { "1": { name: "First Item", tag: "first" }, "2": { name: "Second Item", tag: "second" } }; ``` I want to do something like this: ``` <input type="text" name="serchBox" ng-model="searchByName"> <p ng-repeat="(key, values) in items | filter:{name: searchByName}"> Using both {{key}} and {{values.name}} </p> ``` This is indeed not working. I tried a lot of things and I couldn't make it work properly. I don't want to change my object. I was searching a lot but I didn't find anything that fits my needings.
