• 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 (((((graint or irank) or (ggranddtd or (grained or (grants or migmaints)))) or raw) or gran) or ((gbrain or (brain or (bmain OR main))) or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((grand or hand) or (had or land)) or (bond or bonds)) or (((((graint or irank) or (ggranddtd or (grained or (grants or migmaints)))) or raw) or gran) or ((gbrain or (brain or (bmain OR main))) or rain))) counterinsurgency study ;*.
