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