Hi all Since I upgraded to 3.20 I have a very strange search problem. In the intranet interface searches with a non-ASCII-character show no results. In the opac interface the results are there. For example: "Schärer" results in an error: No results match your search for 'kw,wrdl: Sch�rer' in ... "Scherer" shows some results (in my case 236 items). In /var/log/koha/kb/intranet-error.log I see: [Sat Jun 20 20:34:43.521663 2015] [cgi:error] [pid 20806] [client 192.168.1.52:57404] AH01215: [Sat Jun 20 20:34:43 2015] search.pl: CGI::param called in list context from package main line 421, this can lead to vulnerabilities.

However there is also an entry for "Scherer": [Sat Jun 20 20:37:13.234366 2015] [cgi:error] [pid 20899] [client 192.168.1.52:59580] AH01215: [Sat Jun 20 20:37:13 2015] search.pl: CGI::param called in list context from package main line 421, this can lead to vulnerabilities.

What's wrong? Any suggestions? Beda
