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