Chinese character problem

[handers1234]

Just tried the evaluation ver.I don't know if its bug or not a feature itself.Like the title when i try search with chinese character(Jp language,hiragana to kanji)many of it not convert to correct character and just end up with hiragana instead,somes work like こまったら to 困ったら but when i type ひそか it just end up like that(密か is the correct one).Any fix?
