• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hard) OR (had OR land)) OR (band OR bonds)) OR ((((grand OR (grandtd OR gsandtd)) OR (grawe OR graw)) OR (gran OR (grant OR grants))) 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 (band or bonds)) or ((((grand or (grandtd or gsandtd)) or (grawe OR graw)) or (gran or (grant or grants))) or graint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hard) or (had or land)) or (band or bonds)) or ((((grand or (grandtd or gsandtd)) or (grawe OR graw)) or (gran or (grant or grants))) or graint)) counterinsurgency study ;*.
