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