title: Wordpress $wpdb->get_results returns only one row
body: <p>I'm totally confused.
  I run 2 the same queries, one with $wpdb, the other via mysql_query (also checked via phpmyadmin)
  First query returns ONLY ONE row:</p>
  
  <pre><code>$wpdb-&gt;get_results("SELECT * FROM wp_terms WHERE slug LIKE '%info%' ORDER BY name ASC");
  </code></pre>
  
  <p>mysl_query returns 42 rows. The same result if run the query via phpmyadmin.</p>
  
  <pre><code>$con=mysql_connect(DB_HOST,DB_USER,DB_PASSWORD);
    mysql_selectdb(DB_NAME,$con);
    $res=mysql_query("SELECT * FROM wp_terms WHERE slug LIKE  '%info%' ORDER BY name ASC",$con);
    while($obj=mysql_fetch_object($res)) {
      var_dump($obj);
    }
  </code></pre>
  
  <p>How can it be ??</p>
  
  <pre><code>$wpdb-&gt;show_errors();
  $wpdb-&gt;print_error();
  </code></pre>
  
  <p>show no errors.</p>
