• The words AND, OR and NOT may confuse the search; try adding quotes: "((((grand or hand) or (had or land)) or (bond or bonds)) or (((((san or detail) or grandtd) or (((growe OR grower) or garowe) or rawn)) or (san or draw)) or ((((brain or main) or main) or brains) or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((grand or hand) or (had or land)) or (bond or bonds)) or (((((san or detail) or grandtd) or (((growe OR grower) or garowe) or rawn)) or (san or draw)) or ((((brain or main) or main) or brains) or rain))) counterinsurgency study ;*.
