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