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