AND – narrows a search (e.g. global warming AND United States)
OR – broadens a search (e.g. global warming AND United States OR Canada)
Best to use with synonyms, slang, or related words.
NOT – limits a search (e.g. global warming AND United States NOT Alaska)
Phrase Searching – Place a phrase between quote marks (“”) (e.g. “global warming” AND United States)
Truncation – Use an asterisk (*) at the end of the root of a word to retrieve all variations of the word (e.g. educat* will search for educate, educators, education, educates, …)
Wildcard – Use a question mark (?) to replace one character in a word (e.g. wom?n will search for woman and women)
Limiters – Focus your results by limiting to full text, publication types (e.g. magazines), document type (e.g. article), language, publication date, and more
Articles in Scholarly Journals – Check the limit results box for “Scholarly (Peer Reviewed) Journals”, “Peer reviewed”, or “Scholarly journals” when you search.
Empirical Articles – Limit results to scholarly journals and add the terms “Study” and/or “Studies” to search.
