• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty nang x ho. hieu ((ve cau) OR (ve cac)) luoc van anh lai ((chau tre) or (chay tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang x ho. hieu ((ve cau) OR (ve cac)) luoc van anh lai ((chau tre) OR (chay tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang x ho. hieu ((ve cau) OR (ve cac)) luoc van anh lai ((chau tre) or (chay tren))".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang x ho. hieu ((ve cau) OR (ve cac)) luoc van anh lai ((chau tre) or (chay tren))*.
