• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (far OR had)) OR (san OR (band OR grant))) OR land) OR ((((ghairitt OR (hard OR hairm)) OR heat) OR (((((haro OR hari) OR hartd) OR (har OR shear)) OR (haji OR haiti)) OR hardy)) OR grants)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (far or had)) or (san or (band or grant))) or land) or ((((ghairitt or (hard or hairm)) or heat) or (((((haro OR hari) or hartd) or (har or shear)) or (haji or haiti)) or hardy)) or grants)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (far or had)) or (san or (band or grant))) or land) or ((((ghairitt or (hard or hairm)) or heat) or (((((haro OR hari) or hartd) or (har or shear)) or (haji or haiti)) or hardy)) or grants)) counterinsurgency study ;*.
