• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR rank) OR hand) OR (had OR land)) OR (band OR bonds)) OR (((((grand OR (grant OR graint)) OR gbankstd) OR (((grawd OR (growe OR garowe)) OR raid) OR graw)) OR gran) OR geraint)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or rank) or hand) or (had or land)) or (band or bonds)) or (((((grand or (grant OR graint)) or gbankstd) or (((grawd or (growe or garowe)) or raid) or graw)) or gran) or geraint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or rank) or hand) or (had or land)) or (band or bonds)) or (((((grand or (grant OR graint)) or gbankstd) or (((grawd or (growe or garowe)) or raid) or graw)) or gran) or geraint)) counterinsurgency study ;*.
