其实是很常见的东西,
我看他source 是href=/search?q=blahblah&start=20&sa=N
server 怎么找出20--30 条的东西?
重新搜索一遍?cache ?====> but then you have to use sth to record user's id, e.
g . cookie ...

不对啊,他现在这个样子,每次必须把100个结果都算出来,
再present user 要的那一段,
再加上user 要都浏览一遍,可就是10x10 的白费功夫

Then I think google do a search for like 5 pages each time and cache it on
server-side. So, browsing the within the 5-page neighborhood would only
trigger one query.
