title: Get array of posts without content from WP_Query
body: <p>I use following code to get list of posts</p>
  
  <pre><code>$the_query = new WP_Query($args);
  while ($the_query-&gt;have_posts()) {
      $the_query-&gt;the_post();
      //work with post
  }
  </code></pre>
  
  <p>in this case I get the content and other stuff for each post in the array. But I don't need content, it can be rather big. Can I exclude content from the result array to improve performance?</p>
