• If you are trying to use Boolean operators, they must be ALL CAPS: hoc cac ky nang khoa hoc. hieu ve cac ((xuc van) OR (luc van)) hanh ((vi cua) OR (di cua)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc cac ky nang khoa hoc. hieu ve cac ((xuc van) OR (luc van)) hanh ((vi cua) or (di cua)) cau*".
