The advantage of the Advanced Search is that it allows you to limit your search with filters. The advanced search page is divided into two sections.
This is similar to Thorncat's Basic Search. The key difference is that you have the ability to add additional search boxes.
With search filters you have the option to put limits on your search. Please note: Your results are based on the fields these filters depend upon being completed, which may not always be the case. So, while the filters are helpful, they may not always bring back complete results.
