• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR grand) OR hand) OR (had OR land)) OR (band OR bonds)) OR (((((grant OR irank) OR ((ggranddtd OR ggrainddtd) OR (grained OR graints))) OR raw) OR gran) OR ((gbrain OR gbmain) OR rain))) counterinsurgency study ;~.
• 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 bonds)) or (((((grant or irank) or ((ggranddtd or ggrainddtd) or (grained or graints))) or raw) or gran) or ((gbrain or gbmain) or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand OR grand) or hand) or (had or land)) or (band or bonds)) or (((((grant or irank) or ((ggranddtd or ggrainddtd) or (grained or graints))) or raw) or gran) or ((gbrain or gbmain) or rain))) counterinsurgency study ;*.
