• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or stand) or hand) or (had or land)) or (bank or bonds)) or ((((((grand OR grawd) or irand) or grantdtd) or (grade or trade)) or gran) or (((graint or brain) or geraint) or grain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or stand) or hand) or (had or land)) or (bank or bonds)) or ((((((grand OR grawd) or irand) or grantdtd) or (grade or trade)) or gran) or (((graint or brain) or geraint) or grain))) counterinsurgency study ;*.
