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