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