• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang mai hoi. hieu va ((((cac xuc) OR (chat xuc))) or (cam xuc)) va danh co cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang mai hoi. hieu va ((((cac xuc) OR (chat xuc))) OR (cam xuc)) va danh co cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang mai hoi. hieu va ((((cac xuc) OR (chat xuc))) or (cam xuc)) va danh co cua viet".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang mai hoi. hieu va ((((cac xuc) OR (chat xuc))) or (cam xuc)) va danh co cua viet*.
