#28 searching by pinyin and english can't handle whitespaces

[peng jiang]

searching by pinyin and english can't handle more than one white spaces between 2 characters.
case1:
enter: "take care", correct entries returned.
enter: "take care", nothing returned
case2:
enter: "chun1 tian1", correct entries returned.
enter: "chun1 tian1", nothing returned.

I think we should delete unnecessary white spaces before we pass the input into searching method.

Yes, I agree that outside is the proper place for this functionality.
