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