• Title: Sort by the pages title in alphabetical order/
• Reverse *: Sorts as the corresponding method above, but in reverse order.

F.A.Q.:

• Q) How does refine search work?
• A) The refine search does not actually do a secondary search on the current results. That functionality is unfortunately not available. It is there to maintain the search term you used to get the current results, allowing you to modify it and search again Thankfully the search engine is very fast on a set the size of ours.
  
  
• Q) Does he ht://Dig search engine use synonyms?
• A) Yes it does. It uses a list of word pairs when building its search term internally. Submission of synonyms that would be appropriate for the PGA sites is greatly appreciated!
  
  
• Q) Does ht://Dig support phrase or near matching?
• A) The current stable release we are using has not implemented those features. Phrase matching is in the current beta release.
  
  
• Q) How do I start a new search?
• A) Just clear the search term entry box and enter your new search term, or click on the new search link.
