Google Custom Search
Yep, that's correct. I have integrated Google Custom Search in to dotFiles. In case you didn't notice, there is now a search link in the navigation bar to the right.
It took a bit of doing to get things working the first time around. But, that's because I messed things up when creating the custom search engine. Once I got the CSE working, I spent quite a bit of time playing with the layout, formatting, and theming of the search box and results. I even managed to configure the CSE so that you could search the entire site (all) or the different categories. To search for "http redirect" in the articles section, click on search, enter "http redirect", hit "enter" (or click the magnifying glass, and click on the "Blog" tab. Or you can click this link to see the example.
