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