• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or (band or bond)) or ((sand or stand) or (hand or had))) or (bank or land)) or ((((((graink or (rank OR ranks)) or (grandtsk or (grant or irant))) or gran) or frank) or gbond) or ghana)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or (band or bond)) or ((sand or stand) or (hand or had))) or (bank or land)) or ((((((graink or (rank OR ranks)) or (grandtsk or (grant or irant))) or gran) or frank) or gbond) or ghana)) counterinsurgency study ;*.
