• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ly tang ((ma hoi) or (xa hoi)). hieu van ca dua ban ((hanh ly) OR (hanh ky)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly tang ((ma hoi) OR (xa hoi)). hieu van ca dua ban ((hanh ly) OR (hanh ky)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly tang ((ma hoi) or (xa hoi)). hieu van ca dua ban ((hanh ly) OR (hanh ky)) cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach ly tang ((ma hoi) or (xa hoi)). hieu van ca dua ban ((hanh ly) OR (hanh ky)) cua te*.
