 *   > LATER: build from DB record (stored query) if $savedSearchID is provided
 *   > try to build from $_GET vars, if found

 * NOTE: We should be able to include this mutiple times, with NO side effects
 * since it only builds once. This makes it easy to build an accurate search UI,
 * to embed the results panel in the main search page, and also call separately
