• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky lang xa hoi. hieu ke cau luc bat ((hanh de) OR (hanh ve)) ((cua tre) or (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky lang xa hoi. hieu ke cau luc bat ((hanh de) OR (hanh ve)) ((cua tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky lang xa hoi. hieu ke cau luc bat ((hanh de) OR (hanh ve)) ((cua tre) or (cau treo))".
• Adding a wildcard symbol may retrieve word variants: te sac ky lang xa hoi. hieu ke cau luc bat ((hanh de) OR (hanh ve)) ((cua tre) or (cau treo))*.
