Searches are not case-sensitive.
Enclosing two or more words in double quotes will return
only faculty profiles containing the quoted terms in the
requested order (e.g. a search for "Public Health" will
only return faculty profiles that contain the phrase
'Public Health'.)
Use 'AND' in keyword box to search for words that appear
in any order in a faculty profile (e.g. a search for
'Public AND Health' will return faculty profiles that
contain both the individual words 'Public' and
'Health.')
Using 'OR' in keyword box will broaden your search by
returning faculty profiles that contain keywords on
either side of the word 'OR' (e.g. a search for 'Public
OR Health' will return faculty profiles that contain
either one or both of the words 'Public' and 'Health.' )
A shortened form of your keyword will further broaden
your search (e.g. a search for 'demo' will return
faculty profiles that contain words begin with 'demo,'
such as 'demographic', 'democratic'.)
If search terms are entered without quotes, they are
treated as if a logical 'OR' was placed between each
term. For example, a search for 'Public Health Malaysia'
will return faculty profiles that contain the individual
words 'Public' and/or 'Health' and/or 'Malaysia.'
Quickly enter the first few letters of the faculty last name.
Select the faculty name you are searching for from the
result list.
