Searching result title js code little improvement.

[stevechenzy]

I like it very much, while implementing my own site, I found the return of search string has minor issue with Chinese and "+" sign cannot be fully replaced. here is my suggested improvement.
layout/_default/search/list.html.

var str = (window.location.search).substr(3);
var result = decodeURI(str.replace(/+/g, " "));
document.write(result);
