When searching in korean, the results are not conveient. For example, when I search the word "굿노트", I expect the pages which include "굿노트". But Goodnote shows me all the pages which have "굿" and "노" and "트" separately. This example is same in English : searching "good", then result is all the pages which have "g", "o", "d". This means Goodnote can't understand Korean words perfectly. So searching function is useless for me when I search in Korean.
