Uses AND and OR commands to refine a search in a database, whether in Quick Find, or a Web search engine like Google or Bing, or one of the journal article databases like ERIC
AND narrows a search by adding a new concept e.g. diversity AND education . Only documents with both terms will be retrieved. Google does an automatic AND search – it finds all the terms you type in
OR broadens a search by adding synonyms or variations into a concept e.g. diversity OR multicultural. Any of these terms, or any combination, will be retrieved
To combine terms with both OR and AND, you use parentheses to group the OR’ed terms -- the synonyms -- together in one set. E.g. (diversity OR multicultural) AND education
