• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((irant or iran) or ((granted or (gbraind OR gbbraind)) or iron)) or (hard or had)) or (frank or (franks or (franks or franzks)))) or hand) or land) or bank) or (franz or (gran or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((((irant or iran) or ((granted or (gbraind OR gbbraind)) or iron)) or (hard or had)) or (frank or (franks or (franks or franzks)))) or hand) or land) or bank) or (franz or (gran or rain))) counterinsurgency study ;*.
