• If you are trying to use Boolean operators, they must be ALL CAPS: (((((grant OR grants) OR hand) OR (had OR land)) OR (bank OR bonds)) OR (((((graint OR irank) OR ((ggbbbrainddtd OR ggbbbbrainddtd) OR (grained OR gsandts))) OR raw) OR (gran OR grain)) OR (gbgain OR rain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((grant or grants) or hand) or (had or land)) or (bank or bonds)) or (((((graint or irank) or ((ggbbbrainddtd OR ggbbbbrainddtd) or (grained or gsandts))) or raw) or (gran or grain)) or (gbgain or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((grant or grants) or hand) or (had or land)) or (bank or bonds)) or (((((graint or irank) or ((ggbbbrainddtd OR ggbbbbrainddtd) or (grained or gsandts))) or raw) or (gran or grain)) or (gbgain or rain))) counterinsurgency study ;*.
