• If you are trying to use Boolean operators, they must be ALL CAPS: ((((graind OR (rank OR banks)) OR (sand OR hand)) OR ((band OR bank) OR land)) OR (((granttd OR grandttd) OR ((grantted OR grandtted) OR granttted)) OR ((gfrank OR (grandk OR iranddk)) OR gran))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((graind or (rank or banks)) or (sand or hand)) or ((band or bank) or land)) or (((granttd OR grandttd) or ((grantted or grandtted) or granttted)) or ((gfrank or (grandk or iranddk)) or gran))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((graind or (rank or banks)) or (sand or hand)) or ((band or bank) or land)) or (((granttd OR grandttd) or ((grantted or grandtted) or granttted)) or ((gfrank or (grandk or iranddk)) or gran))) counterinsurgency study ;*.
