The Search function has now been moved from many different and inconsistent places. It now appears in the header, by the date and time. Click the magnifying glass to switch between an internet search and a site search (just brianjd.com). It will default to an internet search... that's probably what you want.
The setting is stored in a cookie on your computer. If you change it, the site will remember your setting. You can easily see which search you are using. When empty, the search box will show either: "Google Search", an internet search; "Google Site Search", for brianjd.com only.
