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