• 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 ((((ghardtt OR harm) OR head) OR (((hardy OR (har OR hart)) OR ((harsh OR hardsh) OR bharti)) OR (hardmidm OR harddm))) 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 ((((ghardtt or harm) or head) or (((hardy or (har or hart)) or ((harsh OR hardsh) or bharti)) or (hardmidm or harddm))) 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 ((((ghardtt or harm) or head) or (((hardy or (har or hart)) or ((harsh OR hardsh) or bharti)) or (hardmidm or harddm))) or grant)) counterinsurgency study ;*.
