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