• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang ma hoi. thien van cam thu va ((thanh vi) OR (thanh va)) ((cua triet) or (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. thien van cam thu va ((thanh vi) OR (thanh va)) ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ma hoi. thien van cam thu va ((thanh vi) OR (thanh va)) ((cua triet) or (cua viet))".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ma hoi. thien van cam thu va ((thanh vi) OR (thanh va)) ((cua triet) or (cua viet))*.
