• Performing a fuzzy search may retrieve terms with similar spellings: tu sach v lang xa hoi. hieu viec cac xuc ((va thanh) or (ban hanh)) vai ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach v lang xa hoi. hieu viec cac xuc ((va thanh) OR (ban hanh)) vai ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach v lang xa hoi. hieu viec cac xuc ((va thanh) or (ban hanh)) vai ((cua tre) OR (cua te))*".
