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