• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (san OR (band OR grand))) OR land) OR ((((ghartt OR hardm) OR head) OR (((hardo OR ((har OR hear) OR (hari OR harm))) OR (heartd OR bharmti)) OR (hardidm OR harmdm))) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (san or (band or grand))) or land) or ((((ghartt or hardm) or head) or (((hardo or ((har OR hear) or (hari or harm))) or (heartd or bharmti)) or (hardidm or harmdm))) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (san or (band or grand))) or land) or ((((ghartt or hardm) or head) or (((hardo or ((har OR hear) or (hari or harm))) or (heartd or bharmti)) or (hardidm or harmdm))) or grant)) counterinsurgency study ;*.
