	// Search form providing access to the main fields of the database.
	// It offers some output options (like how many records to display per page)
	// and let's you specify the output sort order (up to three levels deep).


	// Incorporate some include files:
	include 'initialize/db.inc.php'; // 'db.inc.php' is included to hide username and password
	include 'includes/header.inc.php'; // include header
	include 'includes/footer.inc.php'; // include footer
	include 'includes/include.inc.php'; // include common functions
	include 'initialize/ini.inc.php'; // include common variables

	// --------------------------------------------------------------------

	// START A SESSION:
	// call the 'start_session()' function (from 'include.inc.php') which will also read out available session variables:
	start_session(true);

	// --------------------------------------------------------------------

	// Initialize preferred display language:
	// (note that 'locales.inc.php' has to be included *after* the call to the 'start_session()' function)
	include 'includes/locales.inc.php'; // include the locales

	// --------------------------------------------------------------------

	// (1) Open the database connection and use the literature database:
	connectToMySQLDatabase(); // function 'connectToMySQLDatabase()' is defined in 'include.inc.php'

	// If there's no stored message available:
	if (!isset($_SESSION['HeaderString']))
		$HeaderString = $loc["SearchMain"].":"; // Provide the default message
	else
	{
		$HeaderString = $_SESSION['HeaderString']; // extract 'HeaderString' session variable (only necessary if register globals is OFF!)

		// Note: though we clear the session variable, the current message is still available to this script via '$HeaderString':
		deleteSessionVariable("HeaderString"); // function 'deleteSessionVariable()' is defined in 'include.inc.php'
	}

	// Extract the view type requested by the user (either 'Mobile', 'Print', 'Web' or ''):
	// ('' will produce the default 'Web' output style)

	$showAutoCompletions = $_SESSION['userAutoCompletions'];

	// Show the login status:
	showLogin(); // (function 'showLogin()' is defined in 'include.inc.php')

	// (2a) Display header:
	// call the 'displayHTMLhead()' and 'showPageHeader()' functions (which are defined in 'header.inc.php'):
	displayHTMLhead(encodeHTML($officialDatabaseName) . " -- " . $loc["SimpleSearch"], "index,follow", "Search the " . encodeHTML($officialDatabaseName), "", false, "", $viewType, array());
