• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bond OR (fair OR had)) OR (san OR (band OR grand))) OR land) OR ((((chart OR (gharimm OR gharmmimm)) OR heat) OR (((heart OR har) OR ((harmdimi OR harmd) OR (charti OR chartsi))) OR fairs)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bond or (fair or had)) or (san or (band or grand))) or land) or ((((chart or (gharimm or gharmmimm)) or heat) or (((heart or har) or ((harmdimi or harmd) or (charti OR chartsi))) or fairs)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bond or (fair or had)) or (san or (band or grand))) or land) or ((((chart or (gharimm or gharmmimm)) or heat) or (((heart or har) or ((harmdimi or harmd) or (charti OR chartsi))) or fairs)) or grant)) counterinsurgency study ;*.
