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