Claiming to be the world's most private search engine, ixquick offers the same sort of features as DuckDuckGo and Metager, including not storing any personally-identifiable information like IP address or cookies, using HTTPS for communication, and the use of a proxy to anonymise the user when links are clicked on. It also collates results from a range of search engines contacted anonymously to return results.
Similar to Metager, ixquick also claims increased security through operating outside of the US (in this case, the Netherlands) and thereby not at threat by data collection programs and laws like those in the States. And, similar to DuckDuckGo's Cloud Save, your particular settings for the search engine can optionally be stored through a customised URL (meaning you can bookmark it or cut and paste that in a new browser to restore your settings), which itself can be obfuscated to hide the type of settings you prefer.
Unlike Metager ixquick provides text, video and image search as well as, interestingly, a phone directory search, though we couldn't get it return any useful information for Australia.
