• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR grand) OR hand) OR (had OR land)) OR (bond OR bonds)) OR (((((grant OR rank) OR (ggranddtd OR (grained OR (grants OR (migmaints OR migrants))))) OR raw) OR gran) OR ((gbrain OR bmain) OR rain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or grand) or hand) or (had or land)) or (bond or bonds)) or (((((grant or rank) or (ggranddtd or (grained or (grants or (migmaints OR migrants))))) or raw) or gran) or ((gbrain or bmain) or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or grand) or hand) or (had or land)) or (bond or bonds)) or (((((grant or rank) or (ggranddtd or (grained or (grants or (migmaints OR migrants))))) or raw) or gran) or ((gbrain or bmain) or rain))) counterinsurgency study ;*.
