Better search engines exist for academic use.
Prolific teacher/blogger Richard Byrne at Free Technology for Teachers highlights seven search engines created for student use. Check out his blog post for descriptions of each search engine.
- Sweet Search - a search engine for students where "every web site has been evaluated by our research experts"
- Kid Rex - "Safe search by kids, for kids!" (what's not to love about a site which includes a T-Rex on it's home page?)
- Ref Seek
- Fam Hoo - calls itself the "family friendly" search engine
- Ask Kids
- Wolfram Alpha - the "computational, knowledge engine"
- Google Scholar
