• The words AND, OR and NOT may confuse the search; try adding quotes: "((((grand or hand) or (had or land)) or (bank or bonds)) or (((((gbandddt or (irank or (rank OR ranks))) or (granddtd or (granddts or grantdts))) or raw) or gran) or (gmain or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((grand or hand) or (had or land)) or (bank or bonds)) or (((((gbandddt or (irank or (rank OR ranks))) or (granddtd or (granddts or grantdts))) or raw) or gran) or (gmain or rain))) counterinsurgency study ;*.
