• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky ((lang xa) OR (lang ha)) hoi. hieu qua ca xuc va thanh ((vi cua) or (vai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky ((lang xa) OR (lang ha)) hoi. hieu qua ca xuc va thanh ((vi cua) OR (vai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((lang xa) OR (lang ha)) hoi. hieu qua ca xuc va thanh ((vi cua) or (vai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te sac ky ((lang xa) OR (lang ha)) hoi. hieu qua ca xuc va thanh ((vi cua) or (vai cua)) tre*.
