• If you are trying to use Boolean operators, they must be ALL CAPS: "\"(academies OR academic) AND ((institutes.\" OR institute.\") OR institutions.\")~".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"(academies OR academic) and ((institutes.\\" OR institute.\\") OR institutions.\\")~\"".
• Removing quotes may allow a broader search: (academies OR academic) and ((institutes. OR institute. ) OR institutions. )~.
