• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang xa hoi. hieu he nam thu nam dan sai ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. hieu he nam thu nam dan sai ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. hieu he nam thu nam dan sai ((cua tre) OR (cua triet))*.
