• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR ((hair OR fair) OR had)) OR (sand OR ((band OR bank) OR grand))) OR land) OR ((((ghartt OR (hartdm OR hartm)) OR heat) OR (((harmo OR (har OR harti)) OR (hartd OR bharti)) OR harddm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or ((hair or fair) or had)) or (sand or ((band or bank) or grand))) or land) or ((((ghartt or (hartdm OR hartm)) or heat) or (((harmo or (har or harti)) or (hartd or bharti)) or harddm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or ((hair or fair) or had)) or (sand or ((band or bank) or grand))) or land) or ((((ghartt or (hartdm OR hartm)) or heat) or (((harmo or (har or harti)) or (hartd or bharti)) or harddm)) or grant)) counterinsurgency study ;*.
