[xwiki-devs] HQL case-insensitive queries?

Hello XWiki experts, we seem to be encountering a few HQL queries which return us document names with the wrong casing! E.g. richard instead of Richard. One case where we do not even have any curriki specific is Main/SpaceIndex?space=Coll_anntoniaowens which shows documents of Coll_AnntoniaOwens (only). Is there something I can suspect for this issue? Would there be somewhere a case-insensitivty default in MySQL? (the question at http://stackoverflow.com/questions/7857669/mysql-case-sensitive-query seems to say so). However changing SQL is not really an option. thanks in advance. Paul
