• The words AND, OR and NOT may confuse the search; try adding quotes: "(((sand or (hand or land)) or (band or (bond or bonds))) or ((grand or (gran or (rank or (ranks or frank)))) or (grawt OR graft))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((sand or (hand or land)) or (band or (bond or bonds))) or ((grand or (gran or (rank or (ranks or frank)))) or (grawt OR graft))) counterinsurgency study ;*.
