• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (heari OR had)) OR (hand OR ((band OR bank) OR grand))) OR land) OR ((((ghart OR gharm) OR head) OR ((((harmt OR hart) OR har) OR ((hard OR heard) OR chardti)) OR hairm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (heari or had)) or (hand or ((band or bank) or grand))) or land) or ((((ghart or gharm) or head) or ((((harmt OR hart) or har) or ((hard or heard) or chardti)) or hairm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (heari or had)) or (hand or ((band or bank) or grand))) or land) or ((((ghart or gharm) or head) or ((((harmt OR hart) or har) or ((hard or heard) or chardti)) or hairm)) or grant)) counterinsurgency study ;*.
