Phrase Search Don’t forget to enclose me in double “quotation marks.” Phrase Search (“double quotes”) – A phrase is more than one keyword. Google searches for the exact phrase; the search engine must return documents with the terms in the exact order. 27 27 27 27

32 FYI Not all nations use the .edu (educational) top level domain.
Some use the second level domain .ac. (academic) to designate any academic organization, including museums and research institutions. Germany uses .uni- France and Switzerland do not maintain a second level domain specifically for academic institutions. 32 32
