title: Filter 'Search by keyword' not working
body: <p>I am trying to create Search by keyword action in my project. 
  Here is the code in the view:</p>
  
  <pre><code>&lt;form method="get"&gt;
  &lt;input type="radio" name="news" value="newest"&gt; Newest First
  &lt;input type="radio" name="news" value="keyword"&gt; Keyword Search
  
  &lt;input type="search" name="keyword" id="search" /&gt;
  &lt;button type="submit" value="Search"&gt;&lt;span class="glyphicon glyphicon-search"&gt;&lt;/span&gt;&lt;/button&gt;
  </code></pre>
  
  <p></p>
  
  <p>Here is the model:</p>
  
  <pre><code>public class News
  {
      public int Id { get; set; }
      public string Date { get; set; }
      public string Name { get; set; }
      public string Description { get; set; }
      public string Image { get; set; }
      public string Link { get; set; }
  
  }
  </code></pre>
  
  <p>Here is the controller where it's not working. The Newest First is giving the right data, but the Keyword first just gives every single object of the list.</p>
  
  <pre><code>[HttpGet]
      public ActionResult News(String news = null, String text = null)
      {
          if (news == "newest")
          {
  
              var model =
                  from n in _news
                  orderby n.Date
                  select n;
              return View(model);
          }
          else {
  
              var model =
                  from n in _news
                  .Where(n=&gt; text == null || n.Name.Contains(text))
                  select n;
  
              return View(model);        
          }
  
      }
  </code></pre>
  
  <p>And here are a few of the elements of the News list:</p>
  
  <pre><code>static List&lt;News&gt; _news = new List&lt;News&gt;
      {
  
          new News {
  
              Id = 1,
              Date = "01/01/2017",
              Name = "blabla",
              Description = "blabla",
              Image = "blabla.jpg",
              Link = "dassda"
          },
  
          new News {
  
              Id = 2,
              Date = "vlava",
              Name = "dada",
              Description = "dsadasa",
              Image = "dasdsa.jpg",
              Link = "sdaa"
         };
  </code></pre>
