• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky lang xa hoi. hieu ve ((cam cuc) or (((pham chuc) OR (pham duc)))) ban hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky lang xa hoi. hieu ve ((cam cuc) OR (((pham chuc) OR (pham duc)))) ban hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky lang xa hoi. hieu ve ((cam cuc) or (((pham chuc) OR (pham duc)))) ban hanh vai cua tre*".
