• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sac) OR (thu xac)) ky nang ma hoi. hieu van cam tuc xa danh ((vai va) or (hai va)) thieu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sac) OR (thu xac)) ky nang ma hoi. hieu van cam tuc xa danh ((vai va) OR (hai va)) thieu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sac) OR (thu xac)) ky nang ma hoi. hieu van cam tuc xa danh ((vai va) or (hai va)) thieu".
• Adding a wildcard symbol may retrieve word variants: ((thu sac) OR (thu xac)) ky nang ma hoi. hieu van cam tuc xa danh ((vai va) or (hai va)) thieu*.
