[Koha-devel] Search for cyrillic words not good

[Serhij Dubyk / Сергій Дубик]

I am work with Koha 2.2.7 for Windows, encoding utf-8.
Addition of records works as English and Ukrainian (cyrillic alphabet) well.

But search for cyrillic is case-dependent, although for English words
search does not depend from register.

Also added one cyrillic book to LibLime:
http://koha.liblime.com/cgi-bin/koha/bookshelves/shelves.pl?viewshelf=56
But there search for this book not work at all

It's bug?
