|Use quotation marks.||Place quotation marks around two or more words that you want to search for only in combination, never individually.||“renewable energy”|
|Use “AND” to connect words.||Use “AND” between words when you want to retrieve only articles that include both words.||algae AND energy|
|Use “OR” to choose one or the other.||Use “OR” to find information relating to one of two options but not both. This option works well when you have two terms that mean the same thing and you want to find articles regardless of which term has been chosen for use.||ethanol OR ethyl alcohol|
|Use “NOT” to eliminate likely options.||Use “NOT” to eliminate one category of ideas you know a search term will likely generate.||algae NOT food|
|Use “*” or “?” to include alternate word endings.||Use “*” or “?” to include a variety of word endings. This process is often called using a “wildcard.”||alternate* energy|

When you find a helpful article or Internet site, look for additional search terms and sources that you can follow up on. If you don’t have time to follow up on them all when you find them, include them in your research log for later follow-up. When possible, copy and paste terms and links into your log. When you have to retype, take great care with spelling, spacing, and most of all, attributing direct quotations to their original source.
