• If you are trying to use Boolean operators, they must be ALL CAPS: (((((((band OR ((((migraints OR gbraindts) OR granddtts) OR gain) OR grand)) OR had) OR (bank OR (banks OR irank))) OR (hand OR hard)) OR land) OR bonds) OR ((fran OR (franz OR frankz)) OR (gran OR grant))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((((band or ((((migraints or gbraindts) or granddtts) or gain) or grand)) or had) or (bank or (banks or irank))) or (hand or hard)) or land) or bonds) or ((fran or (franz or frankz)) or (gran OR grant))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((((band or ((((migraints or gbraindts) or granddtts) or gain) or grand)) or had) or (bank or (banks or irank))) or (hand or hard)) or land) or bonds) or ((fran or (franz or frankz)) or (gran OR grant))) counterinsurgency study ;*.
