When the privacy issue was prevalent, I found an alternative search engine that claimed it respected just that: privacy. Although this is an interesting prospect, I actually use DuckDuckGo because of it's easy access to lots of other search engines and information using their !bang system. I won't go into that here but once you've mastered it, there's no going back! ...!
And here's some tools to make it even better. For UK users, I've added a browser search plugin to Mycroft: http://mycroft.mozdev.org/search-engines.html?name=duckduckgo.com
Also, if you use Firefox, there's a way to sync the DDG and browser search boxes:
- First install the SearchBox Sync addon.
- Restart
- Addons > SearchBox Sync > Options
- Select Add...
- Enter the Regular Expression:
https?://([^.]+\.)?duckduckgo\.com+/[^?/]*\?(.*&)?(as_)?q=([^&]+)
Et VoilĂ !
This also works well when you highlight text, right click and select "Search with DDG".
Notice that DDG is the only search engine I have installed: this is because I can always access the others via !g !y !b etc.
