• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bond OR (air OR had)) OR (sand OR (band OR grand))) OR land) OR (((((hairi OR heart) OR gharmm) OR head) OR ((((carmo OR camo) OR hard) OR ((bharti OR haird) OR harmti)) OR hairm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bond or (air or had)) or (sand or (band or grand))) or land) or (((((hairi or heart) or gharmm) or head) or ((((carmo OR camo) or hard) or ((bharti or haird) or harmti)) or hairm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bond or (air or had)) or (sand or (band or grand))) or land) or (((((hairi or heart) or gharmm) or head) or ((((carmo OR camo) or hard) or ((bharti or haird) or harmti)) or hairm)) or grant)) counterinsurgency study ;*.
