• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang mai hoi. hieu ve cham xuc ((van hanh) OR (ban hanh)) ((dai va) or (hoi va)) thieu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang mai hoi. hieu ve cham xuc ((van hanh) OR (ban hanh)) ((dai va) OR (hoi va)) thieu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang mai hoi. hieu ve cham xuc ((van hanh) OR (ban hanh)) ((dai va) or (hoi va)) thieu".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang mai hoi. hieu ve cham xuc ((van hanh) OR (ban hanh)) ((dai va) or (hoi va)) thieu*.
