• If you are trying to use Boolean operators, they must be ALL CAPS: (((sand OR (band OR had)) OR (bank OR land)) OR ((((grandk OR ((grawe OR grand) OR grawde)) OR ((gran OR grain) OR (rain OR main))) 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: "(((sand or (band or had)) or (bank or land)) or ((((grandk or ((grawe or grand) or grawde)) or ((gran OR grain) or (rain or main))) or (grayd or (grayd or grad))) or (grant or brant))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((sand or (band or had)) or (bank or land)) or ((((grandk or ((grawe or grand) or grawde)) or ((gran OR grain) or (rain or main))) or (grayd or (grayd or grad))) or (grant or brant))) counterinsurgency study ;*.
