• Performing a fuzzy search may retrieve terms with similar spellings: (( su sach nha o giai va thuong tin ) or ( te sach xa ((me nguoi) OR (ma nguoi)) san thuong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach nha o giai va thuong tin ) OR ( te sach xa ((me nguoi) OR (ma nguoi)) san thuong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach nha o giai va thuong tin ) or ( te sach xa ((me nguoi) OR (ma nguoi)) san thuong tin ))".
• Adding a wildcard symbol may retrieve word variants: (( su sach nha o giai va thuong tin ) or ( te sach xa ((me nguoi) OR (ma nguoi)) san thuong tin ))*.
