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