• Performing a fuzzy search may retrieve terms with similar spellings: su sach hay quang ma hoi. hieu ve ((cham xuc) OR (cham soc)) ((ho manh) or (va danh)) tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach hay quang ma hoi. hieu ve ((cham xuc) OR (cham soc)) ((ho manh) OR (va danh)) tai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach hay quang ma hoi. hieu ve ((cham xuc) OR (cham soc)) ((ho manh) or (va danh)) tai cua tre*".
