• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hard) OR (had OR land)) OR (band OR bonds)) OR ((((((grand OR irand) OR irank) OR ((granddtd OR grantdtd) OR (irantsed OR irants))) OR raw) OR (gran OR grain)) OR (gbrain OR rain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hard) or (had or land)) or (band or bonds)) or ((((((grand OR irand) or irank) or ((granddtd or grantdtd) or (irantsed or irants))) or raw) or (gran or grain)) or (gbrain or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hard) or (had or land)) or (band or bonds)) or ((((((grand OR irand) or irank) or ((granddtd or grantdtd) or (irantsed or irants))) or raw) or (gran or grain)) or (gbrain or rain))) counterinsurgency study ;*.
