• If you are trying to use Boolean operators, they must be ALL CAPS: ((((band OR ((rank OR frank) OR banks)) OR (san OR stand)) OR ((bond OR bank) OR land)) OR (grand OR (graink OR (gran OR ((grayt OR graints) OR ((growt OR grown) OR graw)))))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((band or ((rank or frank) or banks)) or (san or stand)) or ((bond or bank) or land)) or (grand or (graink or (gran or ((grayt or graints) or ((growt OR grown) or graw)))))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((band or ((rank or frank) or banks)) or (san or stand)) or ((bond or bank) or land)) or (grand or (graink or (gran or ((grayt or graints) or ((growt OR grown) or graw)))))) counterinsurgency study ;*.
