title: Adding "Advanced Search Button" next to search bar
body: <p>I tried many things but could not align "Advanced Search Button" next to search bar. You can see the pic below.</p>
  
  <p>Here are codes I used</p>
  
  <pre><code>&lt;div class="row"&gt;
      &lt;div class="col-md-12"&gt;
  
          &lt;center&gt;
              &lt;form&gt;
                  &lt;div class="form-group"&gt;
                      &lt;div class="input-group" style="width:90%;"&gt;
                          &lt;input class="form-control" name="search" placeholder="ISBN, Yazar yada Kitap adı yazınız" autocomplete="off" autofocus="autofocus" type="text"&gt;
                          &lt;span class="input-group-addon" style="width:1%;"&gt;&lt;a href="#"&gt;&lt;span class="glyphicon glyphicon-search"&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;
                      &lt;/div&gt;
                      &lt;button class="btn btn-default btn-sm"&gt;Advanced Search&lt;/button&gt;
                  &lt;/div&gt;
              &lt;/form&gt;
          &lt;/center&gt;
  
      &lt;/div&gt;@*col-md-12*@
  
  &lt;/div&gt;@*row*@
  </code></pre>
  
  <p>Thanks
