• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR irand) OR (hand OR had)) OR (bank OR land)) OR (((ggsandk OR ((gran OR grand) OR grain)) OR ((iirand OR (igrandd OR iggrandd)) OR (grained OR gained))) OR ((grant OR grants) OR grayts))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or irand) or (hand or had)) or (bank or land)) or (((ggsandk or ((gran or grand) or grain)) or ((iirand or (igrandd or iggrandd)) or (grained or gained))) or ((grant OR grants) or grayts))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or irand) or (hand or had)) or (bank or land)) or (((ggsandk or ((gran or grand) or grain)) or ((iirand or (igrandd or iggrandd)) or (grained or gained))) or ((grant OR grants) or grayts))) counterinsurgency study ;*.
