What's so great about Google's CSE? Well, Jasra says that it delivers the same search experience
that a majority of searchers have shown that they prefer--combined with the personalization options to ensure that the engine fits in with the look and feel of your site.
In addition to taking the work out of building your own (or paying for) a site search engine with lots of bells and whistles, Jasra says that you can easily give users access to the full breadth of your site's great content for free, with Google's CSE.
