• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hand) or (had or land)) or (bond or bonds)) or ((((((grants or irants) or (grank or grant)) or (((grandtd OR gsandtd) or gsandtd) or grantttd)) or graw) or grand) or grain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hand) or (had or land)) or (bond or bonds)) or ((((((grants or irants) or (grank or grant)) or (((grandtd OR gsandtd) or gsandtd) or grantttd)) or graw) or grand) or grain)) counterinsurgency study ;*.
