• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((sand or iran) or (((rani or (grants or (trant OR tran))) or grain) or (igrayd or iron))) or hand) or (rank or frankss)) or san) or land) or bonds) or (trans or ((grant or graw) or rani))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((((sand or iran) or (((rani or (grants or (trant OR tran))) or grain) or (igrayd or iron))) or hand) or (rank or frankss)) or san) or land) or bonds) or (trans or ((grant or graw) or rani))) counterinsurgency study ;*.
