• If you are trying to use Boolean operators, they must be ALL CAPS: (((((irand OR ranks) OR hand) OR (had OR land)) OR (bond OR bonds)) OR (((((((grayt OR grant) OR gray) OR brain) OR (grantdtd OR granted)) OR (grawe OR raw)) OR gran) OR geraint)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((irand or ranks) or hand) or (had or land)) or (bond or bonds)) or (((((((grayt OR grant) or gray) or brain) or (grantdtd or granted)) or (grawe or raw)) or gran) or geraint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((irand or ranks) or hand) or (had or land)) or (bond or bonds)) or (((((((grayt OR grant) or gray) or brain) or (grantdtd or granted)) or (grawe or raw)) or gran) or geraint)) counterinsurgency study ;*.
