The search box works well if you're looking for back for a particular subject being discussed - e.g. licorice tea + GERD would take you back to discussions on that subject. I use the search function quite often, especially when I want to bump up an old but useful thread, e.g. my Barretts one or Sunbeam's Koufman one.
