• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((rand or band) or (sand OR stand)) or (bank or had)) or land) or (bond or bonds)) or (((grank or rank) or grand) or ((gharo or hard) or (((haro or her) or hart) or (hari or cheart))))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((rand or band) or (sand OR stand)) or (bank or had)) or land) or (bond or bonds)) or (((grank or rank) or grand) or ((gharo or hard) or (((haro or her) or hart) or (hari or cheart))))) counterinsurgency study ;*.
