Cuil声称自己是世界上最大的搜索引擎，数据量是Google的三倍（收录网页量）。
Welcome to Cuil—the world’s biggest search engine. The Internet has grown. We think it’s time search did too.
The Internet has grown exponentially in the last fifteen years but search engines have not kept up—until now. Cuil searches more pages on the Web than anyone else—three times as many as Google and ten times as many as Microsoft.
实际情况如何呢？我试用了一下Cuil：
图：Cuil搜索引擎的界面
首先界面，比Google的简洁界面显得更漂亮点，分栏显示结果，每页结果好象能显示11个结果，分三栏。而且就用户输入的关键词，给出相关词和内容，显示在输入框的下边，形成导航页。
然后：我就几个关键词在CUIL进行了搜索，并与Google，Yahoo!，MSN Live!进行对比。
| keywords | seo | sex | news | internet |
| Cuil | 21,400,000 | 250 | 586,600,000 | 426,200,000 |
| 237,000,000 | 831,000,000 | 3,870,000,000 | 2,460,000,000 | |
| Yahoo! | 654,000,000 | 1,890,000,000 | 16,800,000,000 | 7,030,000,000 |
| MSN Live! | 16,600,000 | 1,920,000,000 | 1,550,000,000 | 1,650,000,000 |
结果提示Yahoo！貌似世界上尺寸最大的搜索引擎。
（注：用关键词搜出来的结果总量，有时会被夸大，并且搜索擎引擎的结果是流动的，变化的。这种查询并不能算出一个搜索引擎的真实真实收录量，不过具有一定的参考价值。）
