I'm not sure if this is the same search page that was previously disabled, but the radio button that previously selected between searching for individual posts vs. entire threads on teh
search page I use recently disappeared. This is a significant PITA, as it means that if you're looking for something on biogenesis, you'll get every thread where biogenesis is mentioned, even if it's one post on the fourth page of the thread on some silly supplement where someone says "I buy mine from Biogenesis Nutritionals." Can this please be restored?
