[xwiki-users] Search russian text dont work

Hello! I install XWiki Enterprise 3.5 with MySQL 5.5.17 and Tomcat7 on windows server 2003. Then I download and import default wiki. I switch to russian language in preferences\localisation and try to search word "Песочница" (Sandbox on russian) search url looks like this: server:9080/xwiki/bin/view/Main/Search?text=Песочница On opened page i see "Поиск: Песочница " and no results. I can create, edit and see pages with russian text well. Only search dont work. I also try to search word "Песочница" on site xwiki.org. search url looks like this: http://www.xwiki.org/xwiki/bin/view/Main/Search?text=%26%231055%3B%26%23107… On opened page I see "Search: Песочница" and xwiki nod found russian translation of page Sandbox. Can you suggest something? Thank you
