Search Engines

This site teaches how to effectively use Search Engines and I found it very helpful.


I now understand how to complete a Boolean Search.


It talks about identifying keywords, how to conduct a Boolean Search and an implied Boolean Search, Phrase searching, Alternate Spellings, Title Searches, Domain Searches, Host Searches, URL Searches, Link Searches and more.

Another section has a tutorial on how to research companies.

I like the idea of a Meta Search Engine:
"Meta-search engines (also know as multi-threaded engines) search several major engines at once.... Meta-search engines work best with simple searches."


Dogpile searches 8 search engines and subject directories as well as newsgroups, business news, and newswires. Dogpile supports full Boolean logic and phrase searching.

Vivisimo clusters results from 8 search engines and subject directories into convenient topic categories. Use implied Boolean logic (+/-) and phrase searching.

At MetaCrawler, submit queries to 7 search engines and subject directories. Use implied Boolean logic (+/-) and phrase searching.
