+We did a lot of work in laying the foundation of our app in the last step, so now we'll do
+something simple, and add full text search.  We will also write an end-to-end test, because a good
+end-to-end test is a good friend. It stays with your app, keeps an eye on it, and quickly detects
+regressions.
+
+__`app/index.html`:__
+<pre>
+...
+   Fulltext Search: <input name="query"/>
+
+  <ul class="phones">
+    <li ng:repeat="phone in phones.$filter(query)">
+      {{phone.name}}
+      <p>{{phone.snippet}}</p>
+    </li>
+  </ul>
+...
+</pre>
+__`test/e2e/scenarios.js`:__
+<pre>
+/* jasmine-like end2end tests go here */
+describe('PhoneCat App', function() {
+
+  describe('Phone list view', function() {
+
+    beforeEach(function() {
+      browser().navigateTo('../../app/index.html');
+    });
+
+
+    it('should filter the phone list as user types into the search box', function() {
+      expect(repeater('.phones li').count()).toBe(3);
+
+      input('query').enter('nexus');
+      expect(repeater('.phones li').count()).toBe(1);
+
+      input('query').enter('motorola');
+      expect(repeater('.phones li').count()).toBe(2);
+    });
+  });
+});
+</pre>

+## Discussion:
+
+We continued using the same controller that we set up in Step 2, but we added the following
+features to our app:
+
+* __Search Box:__  A standard HTML `<input>` tag combined with angular's {@link
+angular.Array.filter $filter} utility (added to the repeater) lets a user type in search criteria
+and immediately see the effects of their search on the phone list.  This new code demonstrates the
+following:
+
+   * Two way Data-binding.  This is one of the core features in angular.  When the page loads,
+   angular binds the name of the input box to a variable of the same name in the data model and
+   keeps the two in sync.
+
+In this example, the data that you type into the input box (named __`query`__) is immediately
+available as a filter input in the list repeater (`phone in phones.$filter(`__`query`__`)`).
+Whenever the data model changes and this change causes the input to the repeater to change, the
+repeater will efficiently update the DOM to reflect the current state of the model.
+
+   * Use of `$filter` in a template.  The `$filter` function is one of several built-in {@link
+   angular.Array angular functions} that augment JavaScript arrays during their evaluation as
+   angular expressions. In {@link guide.expression angular expressions}, these array utilities are
+   available as array methods. (They are prefixed with a $ to avoid naming collisions.)
+
+   * `ng:repeat` automatically shrinks and grows the number of phones in the View, via DOM
+   manipulation that is completely transparent to the developer.  If you've written any DOM
+   manipulation code, this should make you happy.
+
+* __CSS:__ We added in some minimal CSS to the file we set up in Step 0: `./css/app.css`.
+
+* __Testing:__  To run the end to end test, open http://localhost:8000/test/e2e/runner.html in
+your browser. This end-to-end test shows the following:
+
+    * Proof that the search box and the repeater are correctly wired together.
+
+    * How easy it is to write end-to-end tests.  This is just a simple test, but the point here is
+    to show how easy it is to set up a functional, readable, end-to-end test.
