• 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 (harmd OR hardy)) OR head) OR (((harddo OR (har OR (harmi OR harm))) OR (hart OR bharmti)) OR harmmidm)) 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 (harmd or hardy)) or head) or (((harddo or (har or (harmi OR harm))) or (hart or bharmti)) or harmmidm)) 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 (harmd or hardy)) or head) or (((harddo or (har or (harmi OR harm))) or (hart or bharmti)) or harmmidm)) or grant)) counterinsurgency study ;*.
