我有一个ng-repeat，我正在尝试对嵌套属性进行过滤。例如，如何job:title在以下集合中对嵌套的进行过滤：
{
"name":"Bob",
"job": {
"title":"farmer",
"difficulty":"medium"
}
},
{
"name":"Sue",
"job": {
"title":"fisher",
"difficulty":"hard"
}
},
{
"name":"Joe",
"job":{
"title":"smith",
"difficulty":"expert"
}
}
我有一个ng-repeat在每次迭代中使用嵌套值的。
<tr ng-repeat="item in items | filter:myFilter ">
<td>{{ item.user.name }}</td>
<td>{{ item.item_name.value }}</td>
</tr>
我希望多个过滤器对这些值中的每一个都独立起作用。我似乎无法弄清楚语法：
<tr>
<td><input type="text" placeholder="Filter by User name" ng-model="myFilter.item.user.name"/></td>
<td><input type="text" placeholder="Filter by Item name" ng-model="myFilter.item.item_name.value"/></td>
</tr>
编辑：json对象的示例

{

}
]
}
]
}
分解为像我这样的假人：
每个过滤器输入元素都有其自己的ng-model值：
<tr>
<td><input ng-model="nameSearch" type="text" placeholder="filter"/></td>
<td><input ng-model="jobSearch" type="text" placeholder="filter"/></td>
</tr>
将过滤器应用于ng-repeat时，迭代对象的json是键（在之前:），而ng-model项（在上面定义）是值（在之后:）：
filter:{json.nested.item:nameSearch, different.nested.item:jobSearch}
应用：
<tr ng-repeat="item in items | filter:{name:nameSearch,job.title:jobSearch}">
<td>{{item.name}}</td>
<td>{{item.job.title}}</td>
</tr>
