// This script takes a user query name (which was passed to the script by use of the 'Recall My Query' form on the main page 'index.php')
// and extracts all saved settings for this particular query from the 'queries' MySQL table. It will then build an appropriate query URL
// and pass that to 'search.php' which will finally display all matching records in list view.
