• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ty hang ha hoi. lieu va nam thuc ((((va thanh) OR (gia thanh))) OR (va tinh)) hoi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ty hang ha hoi. lieu va nam thuc ((((va thanh) OR (gia thanh))) or (va tinh)) hoi cua te".
• Adding a wildcard symbol may retrieve word variants: thuat sach ty hang ha hoi. lieu va nam thuc ((((va thanh) OR (gia thanh))) or (va tinh)) hoi cua te*.
