Internet上的资源无限,如何在浩如烟海的Internet上寻找所需,其中最有效的方法之一,就是使用搜索引擎来查寻各种信息。目前网上的搜索引擎众多,由于每种搜索引擎的收集内容、收集方法等各不相同,使得各搜索引擎各具特色。由于这些搜索引擎的搜索能力各不相同,在寻找某一信息时,可能在这个引擎得到的信息多一些,在那个引擎得到的信息少一些,但是在寻找其它信息时,可能情况就相反了。因此,网民常常需要在众多的搜索引擎中,分别搜索,来回奔波。

Due to the search capabilities of these search engines vary, there may be more information available on this engine when looking for a certain information, and the less information available on that engine, but the reverse may be the case when looking for other information. Therefore, Internet users often need to search in many search engines, respectively, back and forth.
