title: Apply filter only when the input is greater than 3 characters
body: <p>How can I get the results of a ng-repeat by applying a filter of an input only when it is greater than 3 (or N) characters?</p>
  
  <p>I've tried the following (<strong>filter: input.lenght > 3</strong>):</p>
  
  <pre><code>&lt;input type="text" ng-model="input" placeholder="Search"&gt;
  
  &lt;li ng-repeat="detail in details | filter: input.lenght &gt; 3"&gt;
    {{ detail.name }}
  &lt;/li&gt;
  </code></pre>
  
  <p>But it does not work. How can I do what I want? Greetings friends.</p>
  
  <p>Solution:</p>
  
  <pre><code>&lt;input type="text" ng-model="input" ng-minlength="3" placeholder="Search"&gt;
  </code></pre>
