• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) sach - thanh toan he thong duong van ((tan ban) OR (toan ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) sach - thanh toan he thong duong van ((tan ban) OR (toan ban))".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) sach - thanh toan he thong duong van ((tan ban) OR (toan ban))*.
