• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hard) OR (had OR land)) OR (bank OR bonds)) OR ((((((((grant OR grants) OR graint) OR iraqi) OR grained) OR graytdtd) OR (graw OR grow)) OR (((gran OR grand) OR ray) OR brain)) OR raint)) 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 bonds)) or ((((((((grant OR grants) or graint) or iraqi) or grained) or graytdtd) or (graw or grow)) or (((gran or grand) or ray) or brain)) or raint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hard) or (had or land)) or (bank or bonds)) or ((((((((grant OR grants) or graint) or iraqi) or grained) or graytdtd) or (graw or grow)) or (((gran or grand) or ray) or brain)) or raint)) counterinsurgency study ;*.
