• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y dang) OR (2 dang)) van hoc. lieu va cam lo van ((thanh than) OR (thanh thanh)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y dang) or (2 dang)) van hoc. lieu va cam lo van ((thanh than) OR (thanh thanh)) cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y dang) or (2 dang)) van hoc. lieu va cam lo van ((thanh than) OR (thanh thanh)) cua te*.
