• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hand) or (had or land)) or (bond or bonds)) or (((((graint or irank) or (ggranddtd or (grained or (grainddts or migmaints)))) or raw) or gran) or (((gbrain OR grain) or bmain) or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hand) or (had or land)) or (bond or bonds)) or (((((graint or irank) or (ggranddtd or (grained or (grainddts or migmaints)))) or raw) or gran) or (((gbrain OR grain) or bmain) or rain))) counterinsurgency study ;*.
