• If you are trying to use Boolean operators, they must be ALL CAPS: (((rand OR (sand OR (hard OR had))) OR (band OR land)) OR (((((grant OR (grantk OR grants)) OR gran) OR frank) OR (grandt OR (grankt OR grantkt))) OR ghana)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((rand or (sand or (hard or had))) or (band or land)) or (((((grant or (grantk OR grants)) or gran) or frank) or (grandt or (grankt or grantkt))) or ghana)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((rand or (sand or (hard or had))) or (band or land)) or (((((grant or (grantk OR grants)) or gran) or frank) or (grandt or (grankt or grantkt))) or ghana)) counterinsurgency study ;*.
