• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) OR (sach tu)) nang xa hoi. hieu va cam thuc va ((danh di) or (hanh kem)) cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach tu)) nang xa hoi. hieu va cam thuc va ((danh di) OR (hanh kem)) cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach tu)) nang xa hoi. hieu va cam thuc va ((danh di) or (hanh kem)) cua tu".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) OR (sach tu)) nang xa hoi. hieu va cam thuc va ((danh di) or (hanh kem)) cua tu*.
