Using Search Engines Know the Capabilities of the Search Engine How does it search? Does it allow Boolean operators? (and, or, not etc.) Does it allow natural language?
Using Search Engines Select Search Terms Carefully Begin by being as specific and restrictive as possible. Broaden search if necessary using synonyms. Use Boolean operators (and, or, not etc.) Use natural language engines to broaden search.
Using Search Engines Use More Than One Search Engine No single search engine covers the entire Internet. Each Search engine has strengths and weaknesses Choose the search engines most likely to meet your particular research needs.
Using Search Engines Use Meta- Search Engines Carefully Search a variety of search engines simultaneously. Strength: Large number of hits. Weakness: Many extraneous hits. Example: Dogpile, MammaDogpile
