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