• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR ((hair OR air) OR had)) OR (san OR (bond OR grand))) OR land) OR ((((ghartt OR harm) OR head) OR (((harddo OR ((har OR hart) OR (hartdi OR harimmi))) OR (hartd OR bharti)) OR hardidm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or ((hair or air) or had)) or (san or (bond or grand))) or land) or ((((ghartt or harm) or head) or (((harddo or ((har OR hart) or (hartdi or harimmi))) or (hartd or bharti)) or hardidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or ((hair or air) or had)) or (san or (bond or grand))) or land) or ((((ghartt or harm) or head) or (((harddo or ((har OR hart) or (hartdi or harimmi))) or (hartd or bharti)) or hardidm)) or grant)) counterinsurgency study ;*.
