FIX: link error in search page

[dev-onejun]

Hi, me again !

I fix an auto-generated link in the search page on my blog. (At first, I thought the error is emitted because I made a few changes to customize the blog.)

But today, fixing this issue, I think the auto-generated link should be changed like this commits.

Before changing, the code made two / in links. For instance, //study/.... According to the master branch of this repo, the link seems like /type-theme//2014/....

Please tell me if I made mistakes. Thx.
