• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (air OR had)) OR (sand OR (band OR grand))) OR land) OR ((((ghardmtt OR (harmddm OR hartmddm)) OR head) OR (((haro OR (har OR harm)) OR ((harditd OR heart) OR bhartti)) OR harmidm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (air or had)) or (sand or (band or grand))) or land) or ((((ghardmtt or (harmddm OR hartmddm)) or head) or (((haro or (har or harm)) or ((harditd or heart) or bhartti)) or harmidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (air or had)) or (sand or (band or grand))) or land) or ((((ghardmtt or (harmddm OR hartmddm)) or head) or (((haro or (har or harm)) or ((harditd or heart) or bhartti)) or harmidm)) or grant)) counterinsurgency study ;*.
