• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((rand or san) or grawd) or hand) or (had or land)) or (band or bonds)) or ((((((grawd or grant) or frank) or (grandddtd or grawted)) or raw) or (gran OR grand)) or (grain or main))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((rand or san) or grawd) or hand) or (had or land)) or (band or bonds)) or ((((((grawd or grant) or frank) or (grandddtd or grawted)) or raw) or (gran OR grand)) or (grain or main))) counterinsurgency study ;*.
