• If you are trying to use Boolean operators, they must be ALL CAPS: (((rand OR ((hand OR band) OR had)) OR (bank OR land)) OR ((((grandk OR ((grande OR grand) OR grawde)) OR (gran OR grain)) OR (grayd OR (grayd OR grad))) OR (grant OR brant))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((rand or ((hand OR band) or had)) or (bank or land)) or ((((grandk or ((grande or grand) or grawde)) or (gran or grain)) or (grayd or (grayd or grad))) or (grant or brant))) counterinsurgency study ;~".
