• Performing a fuzzy search may retrieve terms with similar spellings: thuat ((sach ly) OR (sach lo)) nang ((x hoi) or (xa hoi)). hieu ve cam luc va hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((sach ly) OR (sach lo)) nang ((x hoi) OR (xa hoi)). hieu ve cam luc va hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((sach ly) OR (sach lo)) nang ((x hoi) or (xa hoi)). hieu ve cam luc va hanh vai cua tre*".
