• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((rand OR hand) or rank) or hard) or (had or land)) or (band or bonds)) or (((((grand or graind) or ((iranktd or ibanktd) or ifranktd)) or grawd) or gran) or (graint or grain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((rand OR hand) or rank) or hard) or (had or land)) or (band or bonds)) or (((((grand or graind) or ((iranktd or ibanktd) or ifranktd)) or grawd) or gran) or (graint or grain))) counterinsurgency study ;*.
