Unlike Google, most databases require you to connect keywords or phrases with "boolean operators". The boolean operators AND, OR, and NOT can be used to broaden and narrow your search. You should always place AND, OR, NOT in capitals - that way they won't be actually searched on as words.
Example Topic: Distance education is one way of addressing disadvantage in educational opportunities in remote Australia, particularly for Aboriginal students.
AND: finds records that contains all the words specified.
EXAMPLE: online learning AND distance education retrieves all the records that contain both online learning and distance education
OR: finds records that contain either or both of the words specified.
EXAMPLE: online learning OR distance education retrieves records that contain either online learning or distance education.
NOT: finds records with the first of the two terms but not the second.
EXAMPLE: online learning NOT distance education retrieves records with online learning, but excludes those records containing distance education.
