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