• If you are trying to use Boolean operators, they must be ALL CAPS: ((((band OR rank) OR (had OR land)) OR (bank OR bond)) OR (((grant OR ((grant OR granted) OR granted)) OR (gran OR (gfranks OR (franks OR (frankss OR franksss))))) OR (grantors OR grantees))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((band or rank) or (had or land)) or (bank or bond)) or (((grant or ((grant or granted) or granted)) or (gran or (gfranks or (franks or (frankss OR franksss))))) or (grantors or grantees))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((band or rank) or (had or land)) or (bank or bond)) or (((grant or ((grant or granted) or granted)) or (gran or (gfranks or (franks or (frankss OR franksss))))) or (grantors or grantees))) counterinsurgency study ;*.
