• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((tu vang) OR (tu lang)) ma hoi. hieu ve cac xuc ((van hang) or (van khang)) di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((tu vang) OR (tu lang)) ma hoi. hieu ve cac xuc ((van hang) OR (van khang)) di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((tu vang) OR (tu lang)) ma hoi. hieu ve cac xuc ((van hang) or (van khang)) di cua te*".
