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