• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or grand) or hand) or (had or land)) or ((band or bank) or bonds)) or (((((graint or irank) or (ggbrainddtd or (gained or gsandts))) or raw) or ((gran OR grain) or stain)) or (gbgain or main))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or grand) or hand) or (had or land)) or ((band or bank) or bonds)) or (((((graint or irank) or (ggbrainddtd or (gained or gsandts))) or raw) or ((gran OR grain) or stain)) or (gbgain or main))) counterinsurgency study ;*.
