Hi all,

i’ve got a problem with words which contain (german) umlauts (ä,ö,  
etc.). Here are some examples:

indexed words: schäfer, hund  
query “hund” -\> hit  
query “Hund” -\> hit  
query “schäfer” -\> hit  
query “Schäfer” -\> no hit

(Same results, if the indexed words have got a capital.)

What can I do to get a case insensitive search? I added these two lines  
to my environment.rb:  
ENV[‘LANG’] = ‘de\_DE.UTF-8@euro’  
ENV[‘LC\_TIME’] = ‘C’

Thanks for help

I fixed the problem. There was no locale “de\_DE.UTF-8@euro” on the  
server. The solution is very simple: remove @euro in case you have  
de\_DE.UTF-8 installed.
