Web search engines use special software programs (called robots, spiders, or crawlers) to find Web pages and list (or index) all words within each one to make searching large quantities of page faster.

Commonly used search engines include Google ( https://www.google.com ) and Bing ( http://www.bing.com ).
In addition to search engines, there are also:
Web Search Engines and related web search tools are helpful for locating background information, news (especially if it’s recent), and public opinion.
However, scholarly information is often not available through a regular web search. If you do find scholarly information through a web search engine, especially if you are off campus, you may be asked for payment to access it. Ohio State Libraries can usually get you what you need without additional payment.
Remember to follow the advice in Source Evaluation to determine whether information you locate online is suitable for your information needs.
See links above. Use of each tool varies. If a search engine has an advanced search, it may include options such as specifying format, language, domain, or date range.
