• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((rand or grand) or grawd) or hard) or (had or land)) or (bank or bonds)) or ((((((grawd or gggraindt) or frank) or (gsanddtd or gbandted)) or raw) or ((gran OR grain) or irant)) or (gain or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((rand or grand) or grawd) or hard) or (had or land)) or (bank or bonds)) or ((((((grawd or gggraindt) or frank) or (gsanddtd or gbandted)) or raw) or ((gran OR grain) or irant)) or (gain or rain))) counterinsurgency study ;*.
