• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach thu) OR (sach tham)) ang xa hoi. lieu va nham thuc ((va thanh) OR (va tinh)) vi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach thu) or (sach tham)) ang xa hoi. lieu va nham thuc ((va thanh) OR (va tinh)) vi cua tu".
• Adding a wildcard symbol may retrieve word variants: tu ((sach thu) or (sach tham)) ang xa hoi. lieu va nham thuc ((va thanh) OR (va tinh)) vi cua tu*.
