• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh y nang ma hoi. ((hieu ve) or (thien van)) cao duc va ((anh vai) OR (anh bai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh y nang ma hoi. ((hieu ve) OR (thien van)) cao duc va ((anh vai) OR (anh bai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh y nang ma hoi. ((hieu ve) or (thien van)) cao duc va ((anh vai) OR (anh bai)) cua tre".
