但是同时，类似的特色和过滤如今出现在多面手搜索引擎上，使其可以更像垂直引擎那样操作。

At the same time, however, similar features and filters are appearing on generalist search-engines, enabling them to act more like vertical engines.

这些海洋滑翔器没有引擎，取而代之的是通过改变浮力在垂直方向上进行操控，水平方向上依靠一对又短又硬的翅膀滑翔前进。

These sea gliders do not have an engine and instead manoeuvre vertically by changing their buoyancy while relying on a pair of short, stubby wings to glide forwards.

其实对于很多垂直搜索引擎来说，都面临着同样一个问题：无法给用户激情让其将这个服务告诉别人，即便这些服务已经十分完美。

This is the same problem that I believe many new vertical search engines suffer from - there is not enough incentive for users to tell their friends about the service, even if it is a great product.
