• Performing a fuzzy search may retrieve terms with similar spellings: so sach ((ky lang) OR (ky tang)) xa hoi. lieu va tham ((xuc ban) or (cuc ban)) thanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ((ky lang) OR (ky tang)) xa hoi. lieu va tham ((xuc ban) OR (cuc ban)) thanh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ((ky lang) OR (ky tang)) xa hoi. lieu va tham ((xuc ban) or (cuc ban)) thanh di cua te".
• Adding a wildcard symbol may retrieve word variants: so sach ((ky lang) OR (ky tang)) xa hoi. lieu va tham ((xuc ban) or (cuc ban)) thanh di cua te*.
