Manfred Kindl a2e8c7fbcb suche.php: Sonderzeichen werden aus dem Suchbegriff entfernt, Bei Dokument-Ergebnissen wird die Berechtigung überprüft, Bei den Content-Ergebnissen werden die Ergebnisse jeder Sprache getrennt angeführt und die Rechte auf den Content überprüft. 
content.class.php: Bei der Funktion "berechtigt" wird nun auch true zurückgegeben, wenn keine Benutzergruppen bei den Rechten angegeben sind.
Funktion "search" gibt nun auch die Sprache des Contents zurück
