• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR band) OR hand) OR (had OR land)) OR (bond OR bonds)) OR (((((grayt OR ((grantd OR irantd) OR frank)) OR ((gbandtd OR gbandtd) OR granttd)) OR graw) OR ((gran OR grain) OR irantd)) OR rain)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or band) or hand) or (had or land)) or (bond or bonds)) or (((((grayt or ((grantd OR irantd) or frank)) or ((gbandtd or gbandtd) or granttd)) or graw) or ((gran or grain) or irantd)) or rain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or band) or hand) or (had or land)) or (bond or bonds)) or (((((grayt or ((grantd OR irantd) or frank)) or ((gbandtd or gbandtd) or granttd)) or graw) or ((gran or grain) or irantd)) or rain)) counterinsurgency study ;*.
