One search engine to consider is Searx [0], you can easily host your own instance locally or on a public facing server [1]. What it does is aggregate search results from multiple engines (Bing, Google, Yahoo...), proxying your request making tracking and profiling impossible.

Yacy is a search engine. Searx passes your query off to other search engines.
