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