• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bond OR (harididmd OR had)) OR (stand OR (band OR grand))) OR land) OR ((((gharddtt OR gharmm) OR heat) OR ((((hardttd OR harddttd) OR (har OR air)) OR ((farmd OR harm) OR harmmti)) OR hairi)) OR grants)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bond or (harididmd or had)) or (stand or (band or grand))) or land) or ((((gharddtt or gharmm) or heat) or ((((hardttd OR harddttd) or (har or air)) or ((farmd or harm) or harmmti)) or hairi)) or grants)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bond or (harididmd or had)) or (stand or (band or grand))) or land) or ((((gharddtt or gharmm) or heat) or ((((hardttd OR harddttd) or (har or air)) or ((farmd or harm) or harmmti)) or hairi)) or grants)) counterinsurgency study ;*.
