• 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 bonds)) OR ((((irand OR (girandtd OR gisandtd)) OR (graw OR raw)) OR (gran OR ((grant OR grandt) OR irand))) 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 bonds)) or ((((irand or (girandtd or gisandtd)) or (graw or raw)) or (gran or ((grant or grandt) or irand))) or rain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand OR grand) or hard) or (had or land)) or (bank or bonds)) or ((((irand or (girandtd or gisandtd)) or (graw or raw)) or (gran or ((grant or grandt) or irand))) or rain)) counterinsurgency study ;*.
