• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky ((lang xa) or (lang van)) hoi. thi van dau thuc va danh ((via cua) OR (gia cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky ((lang xa) OR (lang van)) hoi. thi van dau thuc va danh ((via cua) OR (gia cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky ((lang xa) or (lang van)) hoi. thi van dau thuc va danh ((via cua) OR (gia cua)) tre".
• Adding a wildcard symbol may retrieve word variants: tu cac ky ((lang xa) or (lang van)) hoi. thi van dau thuc va danh ((via cua) OR (gia cua)) tre*.
