• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty tang ((ha hoi) OR (xa hoi)). hieu van cam xuc va hanh ((vai cua) or (dai cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty tang ((ha hoi) OR (xa hoi)). hieu van cam xuc va hanh ((vai cua) OR (dai cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty tang ((ha hoi) OR (xa hoi)). hieu van cam xuc va hanh ((vai cua) or (dai cua)) te*".
