• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu cuc nganh hoa hi đong luc ) OR ( ((nuoc sach) OR (hoc sach)) nganh y khi đong luc ))~.
• Adding a wildcard symbol may retrieve word variants: (( thu cuc nganh hoa hi đong luc ) or ( ((nuoc sach) or (hoc sach)) nganh y khi đong luc ))*.
