• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hari OR had)) OR (hand OR ((band OR bank) OR grand))) OR land) OR ((((ghart OR ghairm) OR head) OR (((hart OR ((har OR harm) OR hear)) OR (hard OR chairdti)) OR fair)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hari or had)) or (hand or ((band or bank) or grand))) or land) or ((((ghart or ghairm) or head) or (((hart or ((har OR harm) or hear)) or (hard or chairdti)) or fair)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hari or had)) or (hand or ((band or bank) or grand))) or land) or ((((ghart or ghairm) or head) or (((hart or ((har OR harm) or hear)) or (hard or chairdti)) or fair)) or grant)) counterinsurgency study ;*.
