亚马逊网址的含义是什么？

我想从亚马逊获取一些信息,但URL似乎非常复杂.有没有人知道亚马逊网址的含义是什么？

例如:Ceiling Fans&Accessories页面的网址是:

http://www.amazon.com/s/ref=lp_2619525011_nr_n_6?rh=n%3A2619525011%2Cn%3A%212619526011%2Cn%3A495362&bbn=2619526011&ie=UTF8&qid=1387193124&rnid=2619526011

是什么意思 ref=lp_2619525011_nr_n_6

是什么意思 rh=n%3A2619525011%2Cn%3A%212619526011%2Cn%3A495362

是什么意思 bbn=2619526011

是什么意思 ie=UTF8

是什么意思 qid=1387193124

是什么意思 rnid=2619526011

https://www.amazon.com/s?rh=
k:-assdhjkadhjkhscue,
n:3375251,
p_n_condition-type:6503254011,
p_72:2661618011,
p_85:2470955011
&page=6
&bbn=2619526011
&ie=UTF8
&qid=1387193124
&rnid=2619526011

rh denotes the factors of query.
k = keyword,
n = category (Sports & Outdoors in this case)
p_n_condition-type = new/used
p_72 = 4 or more stars
p_85 = prime eligible
page = pagination offset(page nos).
qid = the timestamp when the query result was generated.
bbn = browse node numbers.Amazon uses a hierarchy of nodes with a number to the hierarchy to represent collections of items. Each number given is a browse node number.
rnid = random id  for browsing the node.
ie=utf8 = UTF-8 page encoding format.

ie = UTF8出现在man亚马逊页面上是所需的字符编码

qid = 1387193124是生成URL的unix时间戳,在本例中为2015年10月3日格林尼治标准时间12:40:07

ref =也出现在整个网站的许多页面上,并与引用页面有关.几乎像传递HTTP Referer的更明确的方式.

bbn =和rnid =与亚马逊非常混乱的"浏览节点"有关.遗憾的是,此示例中的2619526011与https://www.amazon.com/gp/help/customer/display.html?nodeId=200186090上提供的"浏览树指南"不匹配,后者显示的浏览节点ID为495224

rh =对我来说不清楚,但可能是某些会话状态在页面之间传递.
