• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang ma hoi. lieu ((va tham) or (van tham)) soc va danh ((di cua) OR (de cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. lieu ((va tham) OR (van tham)) soc va danh ((di cua) OR (de cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ma hoi. lieu ((va tham) or (van tham)) soc va danh ((di cua) OR (de cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ma hoi. lieu ((va tham) or (van tham)) soc va danh ((di cua) OR (de cua)) tre*.
