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