Code

<?php

  // Search form submits with POST but redirects to GET. This way we can keep
  // the search query URL clean as a whistle:
  // search/type/keyword+keyword

    // path of its parent (search). It would prevent remembering keywords when
    // switching tabs. This is why we drupal_goto to it from the parent instead.
