There is an SQL-Error in the search plugin with the exact search:

plugins\search\matukio\matukio.php line 176 ff:

case 'exact':
$text = $database->quote(trim($text));
$suche = "\nAND (r.semnum LIKE '%" . $text . "%' OR a.gmaploc LIKE '%" . $text . "%' OR a.target LIKE '%" . $text
. "%' OR a.place LIKE '%" . $text . "%' OR a.teacher LIKE '%" . $text . "%' OR a.title LIKE '%" . $text
. "%' OR a.shortdesc LIKE '%" . $text . "%' OR a.description LIKE '%" . $text . "%' "
. "OR cat.title LIKE '%" . $text . "%')";
break;

should be

case 'exact':
$text = $database->quote('%' . $database->escape($word, true) . '%', false);
$suche = "\nAND (r.semnum LIKE " . $text . " OR a.gmaploc LIKE " . $text . " OR a.target LIKE " . $text
. " OR a.place LIKE " . $text . " OR a.teacher LIKE " . $text . " OR a.title LIKE " . $text
. " OR a.shortdesc LIKE " . $text . " OR a.description LIKE " . $text . " "
. "OR cat.title LIKE " . $text . "";
break;
