• 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 ghardtt) OR hardm) OR head) OR (((hardo OR (har OR harmi)) OR (hartd OR bharmti)) OR (haridm 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 (sand or (band or grand))) or land) or (((((ghartt OR ghardtt) or hardm) or head) or (((hardo or (har or harmi)) or (hartd or bharmti)) or (haridm or harmdm))) 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 ghardtt) or hardm) or head) or (((hardo or (har or harmi)) or (hartd or bharmti)) or (haridm or harmdm))) or grant)) counterinsurgency study ;*.
