The previous version: (#1327)
Search function can not work very well in Chinese, for example, there are lots of Chinese words which length is 2, such as apple/duck/eyes/nose and etc., these words in Chinese are 苹果/鸭子/眼睛/鼻子, so the length of the query limitition should be > 1 , not > 2.
The update version:
Search function can work very well in Chinese word searching. ;-D
