• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or (ranks or banks)) or stand) or ((band or bank) or land)) or (((grant or ((grandtd or (granddtd or grainddtd)) or igrandtd)) or (grants OR grandts)) or ((grawd or (ghandk or graindk)) or gran))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or (ranks or banks)) or stand) or ((band or bank) or land)) or (((grant or ((grandtd or (granddtd or grainddtd)) or igrandtd)) or (grants OR grandts)) or ((grawd or (ghandk or graindk)) or gran))) counterinsurgency study ;*.
