If you're looking for a search engine that churns out extremely high-quality results, then you'll want to take a look at Hakia, a search engine that searches through a collection of carefully vetted, librarian approved sites for the exact answer to your question. For example:
- How much should you stretch before exercise?
- How does ice affect polar bear populations?
- What can go wrong riding a motorcycle?
Hakia also offers you the opportunity to compare each of your search queries to Google, Yahoo, and MSN - just click the Compare to Google button on the right-hand side and you'll get a side by side comparison. I would recommend Hakia for when you need quick, factual answers.

Question and Answer Search Engines: If you're looking for a specific topic with a relatively narrow focus, question and answer search engines might just be what you're looking for. These search engines aggregate the vast resources of the Web into strictly defined categories; in other words, they make it extremely easy to find something.
