• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky sang ma hoi. ((lieu ma) or (lieu phap)) nam thuc va hanh tai ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky sang ma hoi. ((lieu ma) OR (lieu phap)) nam thuc va hanh tai ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky sang ma hoi. ((lieu ma) or (lieu phap)) nam thuc va hanh tai ((cuu tre) OR (cau treo))".
• Adding a wildcard symbol may retrieve word variants: tu sac ky sang ma hoi. ((lieu ma) or (lieu phap)) nam thuc va hanh tai ((cuu tre) OR (cau treo))*.
