• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky van xay hoi. hieu van lam xuc ((va thanh) or (va tinh)) thai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky van xay hoi. hieu van lam xuc ((va thanh) OR (va tinh)) thai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky van xay hoi. hieu van lam xuc ((va thanh) or (va tinh)) thai ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: su sac ky van xay hoi. hieu van lam xuc ((va thanh) or (va tinh)) thai ((cua tre) OR (cua triet))*.
