• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((hoa nang) OR (hoa lang)) ma hoi. ((lieu nano) or (lieu va)) nam thu dan hanh di cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((hoa nang) OR (hoa lang)) ma hoi. ((lieu nano) OR (lieu va)) nam thu dan hanh di cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((hoa nang) OR (hoa lang)) ma hoi. ((lieu nano) or (lieu va)) nam thu dan hanh di cua viet".
