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