• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky ((tang dan) OR (tang luan)) hoi. hieu vu cam xuc va hanh ((vai cua) or (hai cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((tang dan) OR (tang luan)) hoi. hieu vu cam xuc va hanh ((vai cua) OR (hai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((tang dan) OR (tang luan)) hoi. hieu vu cam xuc va hanh ((vai cua) or (hai cua)) te".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((tang dan) OR (tang luan)) hoi. hieu vu cam xuc va hanh ((vai cua) or (hai cua)) te*.
