• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ngang cho hoc. hieu ((((ve cac) OR (vien cac))) OR (va cac)) luc van anh vai cua cay*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ngang cho hoc. hieu ((((ve cac) OR (vien cac))) or (va cac)) luc van anh vai cua cay*".
