• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chau tinh) OR (ha tinh)) - hanh tang luan han huong dan ((toan tap) or (tai cao))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chau tinh) OR (ha tinh)) - hanh tang luan han huong dan ((toan tap) OR (tai cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chau tinh) OR (ha tinh)) - hanh tang luan han huong dan ((toan tap) or (tai cao))*".
