Hmmmmmm Ok!!! However, as many of us use Google as the primary search engine including me, I thought of using ixquick myself for a while to experience its functionality, ease-of-use and relevance of the results to my searches. Following is just an overview.
Ixquick provides an option of including Yahoo, Bing, Wikipedia and other common search engines. I found the search results quite relevant wrt the search keywords, meeting up to atleast a minimum relevance performance I experienced with other search engines. I found the UI to be quite friendly to use. The incorporation of search options for Web, Phone, Video and Pictures keeps it comparable to other search engines' minimum functionality.
To install it as a plugin simply click on "Add ixquick to your browser". See below:
Ixquick also provides a proxy server. Even though ixquick provides you complete privacy, once you click on one of the search results, you are directed to a different server outside the domain of ixquick. Thereupon, you IP Address may be recorded. However, ixquick provides you to click on the "Proxy" link (available below every search result) to open the result throught the ixquick proxy server.
All your HTTP requests/responses are directed via the ixquick proxy providing you the same privacy it claims to offers. It opens the page in a frame and an ixquick header still shows on your page to inform you of the same.
Have fun ixquicking. I would be interested to hear your responses about your experience with it.
