• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR band) OR (had OR land)) OR (bond OR bonds)) OR ((((grand OR gsandtd) OR (grave OR (graw OR grow))) OR ((gran OR grain) OR raw)) OR ((brains OR ((rain OR brain) OR gain)) OR brail))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or band) or (had or land)) or (bond or bonds)) or ((((grand or gsandtd) or (grave or (graw or grow))) or ((gran or grain) or raw)) or ((brains or ((rain OR brain) or gain)) or brail))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or band) or (had or land)) or (bond or bonds)) or ((((grand or gsandtd) or (grave or (graw or grow))) or ((gran or grain) or raw)) or ((brains or ((rain OR brain) or gain)) or brail))) counterinsurgency study ;*.
