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