• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((grand OR graind) OR san) OR hand) OR (had OR land)) OR (bank OR bonds)) OR ((((((graint OR graft) OR trained) OR grantsed) OR (race OR raw)) OR (gran OR grant)) OR graint)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((grand OR graind) or san) or hand) or (had or land)) or (bank or bonds)) or ((((((graint or graft) or trained) or grantsed) or (race or raw)) or (gran or grant)) or graint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((grand OR graind) or san) or hand) or (had or land)) or (bank or bonds)) or ((((((graint or graft) or trained) or grantsed) or (race or raw)) or (gran or grant)) or graint)) counterinsurgency study ;*.
