我们可以料想,当一个地址被搜捕器发现并且出现在索引中,直
到这两步过程完成网站才能被查询到.
最后,每个搜索引擎中心都是一个大的运算器,他们可以
将要找信息中的关键词与索引中的与之匹配的关键词进行对照,
并将运算器找出的结果按照最相关的程度排序
因为搜捕器,造成指数,以及每个搜索引擎的搜索运算法则的不同,
通过不同的搜索引擎搜索会得到不同的结果和排名.
这就解释了输入相同的关键字用hotbot搜索出现的前十个网址和用Alta Vista
搜索出来的前十个网址结果不一样的原因
另外,许多,但不是全部.搜索效果还和网页标记有关,
不可视的描述文件内容的标签也可以作为网页内容被编入索引的方式
结果,正确的实用网页标记也可以提升这个网址被搜索时的排名
以上译文仅供参考
翻译这种文章简直就是痛苦死了应该让计算机系的人来翻译

ween the time a site has been“spidered”and when it appears in a search index.Until this two-step process has been completed,a site remains unavailable to search queries.
Finally,the heart of each search engine is an algorithm that matches keyword queries against the information in the index,ranking results in the order the algorithm deems most relevant.
Because the spiders,resulting indexes,and search algorithms of each search engine differ,so do the search results and rankings across the various search engines.This explains why a top 10 site in HotBot may not appear near the top of Alta Vista when the same keyword search criterion is entered.
In addition,many,but not all,search utilities also reference metatags—invisible HTML tags within documents that describe their content—as a way to control how content is indexed.As a result,proper use of metatags throughout a site can also boost search engine ranking.
