• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (sand OR (band OR grand))) OR land) OR ((((ghartt OR hardm) OR heat) OR (((hartmo OR (((har OR harmd) OR harmd) OR hari)) OR ((hartd OR hart) OR bharmti)) OR hartidm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (sand or (band or grand))) or land) or ((((ghartt or hardm) or heat) or (((hartmo or (((har or harmd) or harmd) or hari)) or ((hartd OR hart) or bharmti)) or hartidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (sand or (band or grand))) or land) or ((((ghartt or hardm) or heat) or (((hartmo or (((har or harmd) or harmd) or hari)) or ((hartd OR hart) or bharmti)) or hartidm)) or grant)) counterinsurgency study ;*.
