angular.js - angular filter问题
下面是angular官网上讲解filter的代码，有些地方没看懂，辛苦各位大神赐教了。
<p ng-init="friends = [{name:'John', phone:'555-1276'},
{name:'Mary', phone:'800-BIG-MARY'},
{name:'Mike', phone:'555-4321'},
{name:'Adam', phone:'555-5678'},
{name:'Julie', phone:'555-8765'},
{name:'Juliette', phone:'555-5678'}]"></p>
Search: <input ng-model="searchText">
<table id="searchTextResults">
<tr><th>Name</th><th>Phone</th></tr>
<tr ng-repeat="friend in friends | filter:searchText">
<td>{{friend.name}}</td>
<td>{{friend.phone}}</td>
</tr>
</table>
<hr>
Any: <input ng-model="search.$"> <br>
Name only <input ng-model="search.name"><br>
Phone only <input ng-model="search.phone"><br>
Equality <input type="checkbox" ng-model="strict"><br>
<table id="searchObjResults">
<tr><th>Name</th><th>Phone</th></tr>
<tr ng-repeat="friendObj in friends | filter:search:strict">
<td>{{friendObj.name}}</td>
<td>{{friendObj.phone}}</td>
</tr>
</table>界面显示效果：
当勾选Equality时，下面的内容不会显示出来
代码中对应的是
不明白它的filter:search:strict是怎么起作用的？为什么什么都不能显示了？
