• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (san OR (band OR grand))) OR land) OR ((((charmts OR (ghartmm OR gharmtmm)) OR head) OR (((heart OR har) OR ((hartmi OR harddid) OR (chariti OR chartts))) OR hairm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (san or (band or grand))) or land) or ((((charmts or (ghartmm OR gharmtmm)) or head) or (((heart or har) or ((hartmi or harddid) or (chariti or chartts))) or hairm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (san or (band or grand))) or land) or ((((charmts or (ghartmm OR gharmtmm)) or head) or (((heart or har) or ((hartmi or harddid) or (chariti or chartts))) or hairm)) or grant)) counterinsurgency study ;*.
