• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR grawd) OR hand) OR (had OR land)) OR (band OR bonds)) OR ((((((grawd OR (grandt OR grant)) OR frank) OR (gsanddtd OR granted)) OR raw) OR gran) OR (ggain OR rain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or grawd) or hand) or (had or land)) or (band or bonds)) or ((((((grawd or (grandt OR grant)) or frank) or (gsanddtd or granted)) or raw) or gran) or (ggain or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or grawd) or hand) or (had or land)) or (band or bonds)) or ((((((grawd or (grandt OR grant)) or frank) or (gsanddtd or granted)) or raw) or gran) or (ggain or rain))) counterinsurgency study ;*.
