• If you are trying to use Boolean operators, they must be ALL CAPS: ((((hand OR (rank OR ranks)) OR (sand OR stand)) OR ((band OR bank) OR land)) OR (grand OR ((grank OR (irank OR frank)) OR ((gran OR (iran OR iron)) OR ((grant OR grawt) OR grawt))))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((hand or (rank or ranks)) or (sand or stand)) or ((band or bank) or land)) or (grand or ((grank or (irank or frank)) or ((gran or (iran OR iron)) or ((grant or grawt) or grawt))))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((hand or (rank or ranks)) or (sand or stand)) or ((band or bank) or land)) or (grand or ((grank or (irank or frank)) or ((gran or (iran OR iron)) or ((grant or grawt) or grawt))))) counterinsurgency study ;*.
