• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ly hang xa hoi. thi van cau ((phuc va) or (chuc va)) hanh vai ((cuu tre) OR (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly hang xa hoi. thi van cau ((phuc va) OR (chuc va)) hanh vai ((cuu tre) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly hang xa hoi. thi van cau ((phuc va) or (chuc va)) hanh vai ((cuu tre) OR (cau tren))".
