User page callbacks for the search module.

Code

function search_view($module = NULL, $keys = '') {
  $info = FALSE;
  $keys = trim($keys);

  // Also try to pull search keywords out of the $_REQUEST variable to
  // support old GET format of searches for existing links.

  }

    // No path or invalid path: find the default module. Note that if there
    // are no enabled search modules, this function should never be called,
    // since hook_menu() would not have defined any search paths.

  // Process the search form. Note that if there is $_POST data,
  // search_form_submit() will cause a redirect to search/[module path]/[keys],
  // which will get us back to this page callback. In other words, the search
  // form submits with POST but redirects to GET. This way we can keep
  // the search query URL clean as a whistle.
