• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (sand OR (bank OR grand))) OR land) OR ((((ghartttt OR hartdm) OR heat) OR ((((harms OR harm) OR ((har OR harmd) OR harti)) OR (harmdtd OR bhart)) OR hartidm)) OR grants)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (sand or (bank or grand))) or land) or ((((ghartttt or hartdm) or heat) or ((((harms OR harm) or ((har or harmd) or harti)) or (harmdtd or bhart)) or hartidm)) or grants)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (sand or (bank or grand))) or land) or ((((ghartttt or hartdm) or heat) or ((((harms OR harm) or ((har or harmd) or harti)) or (harmdtd or bhart)) or hartidm)) or grants)) counterinsurgency study ;*.
