• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (air OR had)) OR (sand OR ((band OR bank) OR grand))) OR land) OR ((((ghartt OR harm) OR heat) OR ((((hardo OR harddy) OR har) OR (((hard OR hartd) OR heart) OR bharti)) OR hairidm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (air or had)) or (sand or ((band or bank) or grand))) or land) or ((((ghartt or harm) or heat) or ((((hardo or harddy) or har) or (((hard OR hartd) or heart) or bharti)) or hairidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (air or had)) or (sand or ((band or bank) or grand))) or land) or ((((ghartt or harm) or heat) or ((((hardo or harddy) or har) or (((hard OR hartd) or heart) or bharti)) or hairidm)) or grant)) counterinsurgency study ;*.
