• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty dung ((tai hoi) OR (tai hai)). hieu van chat xuc ((va thanh) or (gia thanh)) vai cua tuc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty dung ((tai hoi) OR (tai hai)). hieu van chat xuc ((va thanh) OR (gia thanh)) vai cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty dung ((tai hoi) OR (tai hai)). hieu van chat xuc ((va thanh) or (gia thanh)) vai cua tuc".
