• If you are trying to use Boolean operators, they must be ALL CAPS: ((((grant OR hard) OR (had OR land)) OR (band OR bonds)) OR (((((((gray OR ray) OR irantts) OR rain) OR granttd) OR (((grawe OR grace) OR grower) OR raw)) OR gran) OR (raint OR rainy))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((grant or hard) or (had or land)) or (band or bonds)) or (((((((gray or ray) or irantts) or rain) or granttd) or (((grawe OR grace) or grower) or raw)) or gran) or (raint or rainy))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((grant or hard) or (had or land)) or (band or bonds)) or (((((((gray or ray) or irantts) or rain) or granttd) or (((grawe OR grace) or grower) or raw)) or gran) or (raint or rainy))) counterinsurgency study ;*.
