• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR grand) OR hard) OR (had OR land)) OR (bank OR bond)) OR (((((grains OR rains) OR (grantdtd OR (grained OR gainfed))) OR graw) OR (gran OR (grant OR grayt))) OR (grains OR rain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or grand) or hard) or (had or land)) or (bank or bond)) or (((((grains or rains) or (grantdtd or (grained or gainfed))) or graw) or (gran or (grant OR grayt))) or (grains or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or grand) or hard) or (had or land)) or (bank or bond)) or (((((grains or rains) or (grantdtd or (grained or gainfed))) or graw) or (gran or (grant OR grayt))) or (grains or rain))) counterinsurgency study ;*.
