不要惊讶于这些引擎返回的页面数量不同，因为它们都有各自建立页面的索引的算法。

Do not be surprised if the number of pages returned by the search engines varies widely as they each have their own unique algorithms for indexing pages.

它取代了2004开始试探的最初索引算法，它已经证明在处理大量和非结构化数据集时更有效。

It replaced the original indexing algorithms and heuristics in 2004, given its proven efficiency in processing very large, unstructured datasets.

你可能会对域名的年龄也是搜索引擎算法的一个因子感到惊讶。

You might be surprised to learn that domain age is also a factor in the search engine algorithm.

And then, when I got- I'm also going to count how many comparisons I do, just so I can see how much work I do here, and then notice what it does.

并能看到算法干了些什么-,然后是如果这个索引,比数组的大小小的话，就意味着还没检索到数组的最后。
