• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR ((hair OR air) OR had)) OR (san OR (bond OR grand))) OR land) OR ((((ghartt OR (hartd OR (harth OR hart))) OR heat) OR ((((hartm OR harmi) OR har) OR (hardmid OR bharti)) OR hartidm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or ((hair or air) or had)) or (san or (bond or grand))) or land) or ((((ghartt or (hartd or (harth OR hart))) or heat) or ((((hartm or harmi) or har) or (hardmid or bharti)) or hartidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or ((hair or air) or had)) or (san or (bond or grand))) or land) or ((((ghartt or (hartd or (harth OR hart))) or heat) or ((((hartm or harmi) or har) or (hardmid or bharti)) or hartidm)) or grant)) counterinsurgency study ;*.
