• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (hoc thieu)) sach - ((hanh trong) OR (anh trong)) thuat thong cong van chat co~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (hoc thieu)) sach - ((hanh trong) OR (anh trong)) thuat thong cong van chat co~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (hoc thieu)) sach - ((hanh trong) OR (anh trong)) thuat thong cong van chat co*.
