• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach tu) OR (sach y)) hang hai hoi. lieu va ((nam xua) OR (nam mua)) van quan va cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach tu) or (sach y)) hang hai hoi. lieu va ((nam xua) OR (nam mua)) van quan va cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach tu) or (sach y)) hang hai hoi. lieu va ((nam xua) OR (nam mua)) van quan va cua tre*.
