• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach ky lang xa hoi. hieu ve cam xuc ((van hanh) or (ban hanh)) ((vi cua) OR (di cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ky lang xa hoi. hieu ve cam xuc ((van hanh) OR (ban hanh)) ((vi cua) OR (di cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ky lang xa hoi. hieu ve cam xuc ((van hanh) or (ban hanh)) ((vi cua) OR (di cua)) te*".
