新方法

老方式
http://www.google.com/search?q=stackoverflow
磅/哈希符号通常用作页面的一部分的锚点。
除了更短的网址，Google可以获得什么好处？似乎反对搜索引擎惯例，但是再次Google设置约定。有什么问题可以看到这种方法吗？
UPDATE
要测试自己使用www.google.com的一般搜索框。你会得到一些其他的垃圾在url，但q =之前的部分是我提到的这个问题。
更新2
看起来这可能是一个实验性的功能，他们正在随机使用者进行测试，因为有些人被重新路由到搜索中？结果当试图去#结果。
更新3
从对话here看来，这已经推出给所有的Firefox用户使用主要的google.com网站进行搜索。
摘录
4/27/09
The # in query parameters is a
separate experiment that the search
team was doing (AJAX based search
results pages) that started some time
back. It was discussed quite fervently
in the Yahoo Web Analytics discussion
group a few months ago. Random groups
of people were/are assigned to be a
part of the experiment,and that
caused all the keyword data for that
user to dissapear from every Analytics
tool. It looks like the experiment is
still going on.4/28/09 The # in query parameters
appears to have been rolled out to all
Firefox users on www.google.com
SERP`s,so this must have passed the
testing stage. I am speculating that
FireFox is able to handle AJAX better
that IE,thus it has not been rolled
out to IE users.5/1/09 When I dug into the SERP’s
pages it looks like Google initially
puts the websites “true” URL in the
link,but once the link is clicked the
URL is replaced with a Google redirect
URL of the form
www.google.com/url?q=flowers&blahblahblah.
That redirect URL is what shows up in
the HTTP referrer field and what gets
reported by the web browser (and
therefore the Analytics tools).
通过使用哈希，它们可以通过允许它在浏览器元素中保留一个项目来保存在“内存”中。添加哈希还会为页面创建一个历史记录对象。这可以保持前进和后退功能，同时允许他们使用AJAX处理您的搜索。基本上这意味着他们只需要获取加载整个页面所需的HTTP标头的一部分，而不会丢失满载的功能，可以更快地处理您的搜索。
