I have always used Google Custom Search to search my websites. Yesterday though, I felt I wanted to test Drupal Search Box. Thinking it would be very obvious, I enabled the search module in "admin/build/modules/list" and configured it in "/admin/settings/search". Confident I had configured the module properly, I tested the search box but nothing came out. A quick Google Search said that I needed to fix user permissions. I then went to "admin/user/permissions" and gave permission to anonymous and authenticated users.
