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