• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or hard) or (band or bond)) or (had or land)) or (bank or bonds)) or (((((ggranddt or frank) or (gbanddtd or (irants or ghandes))) or raw) or grant) or (((grain OR ggain) or gbrain) or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or hard) or (band or bond)) or (had or land)) or (bank or bonds)) or (((((ggranddt or frank) or (gbanddtd or (irants or ghandes))) or raw) or grant) or (((grain OR ggain) or gbrain) or rain))) counterinsurgency study ;*.
