• 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 ((((gharddtt OR harm) OR head) OR (((harddo OR (har OR hardt)) OR (hardsh OR bharti)) OR (hardmidm OR (harddm OR hardddm)))) 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 ((((gharddtt or harm) or head) or (((harddo or (har or hardt)) or (hardsh or bharti)) or (hardmidm or (harddm OR hardddm)))) 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 ((((gharddtt or harm) or head) or (((harddo or (har or hardt)) or (hardsh or bharti)) or (hardmidm or (harddm OR hardddm)))) or grant)) counterinsurgency study ;*.
