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