• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR sand) OR (stand OR (hand OR had))) OR (bond OR land)) OR (((((graind OR granddtk) OR (gran OR grandts)) OR frank) OR ((grande OR grandde) OR grandkt)) OR ghana)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or sand) or (stand or (hand or had))) or (bond or land)) or (((((graind or granddtk) or (gran or grandts)) or frank) or ((grande OR grandde) or grandkt)) or ghana)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or sand) or (stand or (hand or had))) or (bond or land)) or (((((graind or granddtk) or (gran or grandts)) or frank) or ((grande OR grandde) or grandkt)) or ghana)) counterinsurgency study ;*.
