• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sac) OR (thu xac)) ky nang x hoi. lieu va ca lao va danh vai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sac) OR (thu xac)) ky nang x hoi. lieu va ca lao va danh vai ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: ((thu sac) OR (thu xac)) ky nang x hoi. lieu va ca lao va danh vai ((cua tre) or (cua te))*.
