• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ty ((nang cho) OR (ngang cho)) hoc. thien van cac ((xuc van) OR (luc van)) anh vi cua cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ty ((nang cho) OR (ngang cho)) hoc. thien van cac ((xuc van) or (luc van)) anh vi cua cau*".
