• Performing a fuzzy search may retrieve terms with similar spellings: su sai ((ky dang) or (ky nang)) xa hoi. hieu van cam xuc tan anh tai ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ((ky dang) OR (ky nang)) xa hoi. hieu van cam xuc tan anh tai ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ((ky dang) or (ky nang)) xa hoi. hieu van cam xuc tan anh tai ((cuu tre) OR (cau treo))".
• Adding a wildcard symbol may retrieve word variants: su sai ((ky dang) or (ky nang)) xa hoi. hieu van cam xuc tan anh tai ((cuu tre) OR (cau treo))*.
