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