You still can't sync custom search engines in Google Chrome, and that makes tasks like site-specific searches a pain. There are loads of extensions available which can handle the chore, of course, and one worth checking out is Omnibox Site Search.

Once installed, you simply type the letter s and press space to invoke a Google-powered site search for the domain you're currently visiting. The top five matches load in a flash, and you can also click through to Google via the top link for complete results. It's a fast, simple way to get results which are limited to a specific domain -- and as we know from experience, Google search is nearly always a lot better than most on-site search boxes.
