How do I configure Auto Suggest for my Drupal application?

To use Auto Suggest, complete the following:

• Enable Auto Suggest in the Site Search user interface.
  This triggers the backend server to start building the dictionary using the search history.
• Build the search history dictionary.
  Acquia recommends that you use a sliding window of the last 90 days to build the dictionary. You can seed the dictionary by adding a few terms.
• Configure the settings in Drupal as specified in Drupal Auto-Suggest.
