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