• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach nhanh chong thai đong luc ) OR ( su ((vach tran) OR (sach tranh)) hoang khi đong luc ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach nhanh chong thai đong luc ) or ( su ((vach tran) OR (sach tranh)) hoang khi đong luc ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach nhanh chong thai đong luc ) or ( su ((vach tran) OR (sach tranh)) hoang khi đong luc ))*.
