• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (sand OR (bond OR grand))) OR land) OR ((((ghartt OR hardly) OR head) OR ((((haro OR harmdly) OR (har OR hari)) OR ((harmdtd OR hartmdtd) OR bhartti)) OR haridm)) 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 (bond or grand))) or land) or ((((ghartt or hardly) or head) or ((((haro or harmdly) or (har or hari)) or ((harmdtd OR hartmdtd) or bhartti)) or haridm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (sand or (bond or grand))) or land) or ((((ghartt or hardly) or head) or ((((haro or harmdly) or (har or hari)) or ((harmdtd OR hartmdtd) or bhartti)) or haridm)) or grant)) counterinsurgency study ;*.
