Regular Expression Search

There's nothing regular about Regex. All I needed was to search for the text "SDB" and ".com" with any characters in between. Regex syntax is bewildering and unnecessarily complex. For goodness sake, all I want to do an in page search, not program a missile system. Regex may as well be Malbolge for the use it is. Whatever happened to a search using * and ? as wildcards? In any case, the extension does nothing at all when I came to type in my first attempt. No feedback or activity indicator, nothing! The lack of feedback means I can't say whether it's the regex or extension at fault.
