• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky tang ma hoi. lieu va nam ((thuc xa) OR (thuc xay)) hanh ((tai cuu) or (tai buu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky tang ma hoi. lieu va nam ((thuc xa) OR (thuc xay)) hanh ((tai cuu) OR (tai buu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky tang ma hoi. lieu va nam ((thuc xa) OR (thuc xay)) hanh ((tai cuu) or (tai buu)) tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky tang ma hoi. lieu va nam ((thuc xa) OR (thuc xay)) hanh ((tai cuu) or (tai buu)) tre*.
