• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y dang) OR (_ dang)) van hoc. lieu va ((cam lo) OR (cam o)) van thanh than cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y dang) or (_ dang)) van hoc. lieu va ((cam lo) OR (cam o)) van thanh than cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y dang) or (_ dang)) van hoc. lieu va ((cam lo) OR (cam o)) van thanh than cua te*.
