The DuckDuckGo (DDG) search engine aggregates content to provide search results while offering significant privacy features. My favorite search shortcut in DDG is its version of the Google site: command. Place an exclamation point before the site you want to search–for example, “private investigator” !facebook. The exclamation point directs the search to a specific site. In this case, you will have to login to your Facebook account to see the results.
