title: How to set default sort by value in yii2?
body: <p>Is it possible to sort using value not using column name?</p>
  
  <p>For example, </p>
  
  <pre><code>$dataProvider = new ActiveDataProvider([
          'query' =&gt; $query,
          'sort'=&gt; ['defaultOrder' =&gt; ['id' =&gt; 100]]
      ]);
  </code></pre>
  
  <p>I know i can easily do this with controller or adding params but i want to do it using <code>search()</code> function.</p>
  
  <p>By default, sorting works with column name, So, i am finding new workaround for sort by value.</p>
