• Performing a fuzzy search may retrieve terms with similar spellings: so ((sach ky) OR (sac ky)) nang xa hoi. lieu va chai cua gia thanh vi ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach ky) OR (sac ky)) nang xa hoi. lieu va chai cua gia thanh vi ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach ky) OR (sac ky)) nang xa hoi. lieu va chai cua gia thanh vi ((cua tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: so ((sach ky) OR (sac ky)) nang xa hoi. lieu va chai cua gia thanh vi ((cua tre) or (cua triet))*.
