• If you are trying to use Boolean operators, they must be ALL CAPS: (((((graint OR grad) OR (hand OR hard)) OR (had OR land)) OR ((band OR bond) OR bonds)) OR ((((((grad OR grande) OR frank) OR ((graindtddtd OR ggaindtddtd) OR granted)) OR raw) OR gran) OR (gbrain OR rain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((graint or grad) or (hand OR hard)) or (had or land)) or ((band or bond) or bonds)) or ((((((grad or grande) or frank) or ((graindtddtd or ggaindtddtd) or granted)) or raw) or gran) or (gbrain or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((graint or grad) or (hand OR hard)) or (had or land)) or ((band or bond) or bonds)) or ((((((grad or grande) or frank) or ((graindtddtd or ggaindtddtd) or granted)) or raw) or gran) or (gbrain or rain))) counterinsurgency study ;*.
