• 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 hartdm) OR head) OR (((((haro OR hardo) OR hardy) OR (har OR hari)) OR (hardtd 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 hartdm) or head) or (((((haro OR hardo) or hardy) or (har or hari)) or (hardtd or bhartti)) or haridm)) or grant)) counterinsurgency study ;~".
