• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (hartd OR (band OR grand))) OR land) OR ((((ghearttt OR harm) OR heat) OR ((((harmo OR haro) OR (har OR hardti)) OR ((harttd OR farmth) OR bhartti)) 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 (hartd or (band or grand))) or land) or ((((ghearttt or harm) or heat) or ((((harmo OR haro) or (har or hardti)) or ((harttd or farmth) or bhartti)) or harmdm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (hartd or (band or grand))) or land) or ((((ghearttt or harm) or heat) or ((((harmo OR haro) or (har or hardti)) or ((harttd or farmth) or bhartti)) or harmdm)) or grant)) counterinsurgency study ;*.
