• Performing a fuzzy search may retrieve terms with similar spellings: vu san ((ky tang) OR (ky dang)) mai hoi. hieu ve cam xuc ((va xanh) or (va anh)) dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ((ky tang) OR (ky dang)) mai hoi. hieu ve cam xuc ((va xanh) OR (va anh)) dai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ((ky tang) OR (ky dang)) mai hoi. hieu ve cam xuc ((va xanh) or (va anh)) dai cua tre*".
