• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty dang xay hoi. thien van bac xuc va ((nhanh hai) or (nhanh thai)) ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty dang xay hoi. thien van bac xuc va ((nhanh hai) OR (nhanh thai)) ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty dang xay hoi. thien van bac xuc va ((nhanh hai) or (nhanh thai)) ((cua tre) OR (cua te))".
