• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc sach) OR (hoc sach)) ky nang x hoi. lieu va nam thu dat ((thanh doi) OR (thanh do)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) or (hoc sach)) ky nang x hoi. lieu va nam thu dat ((thanh doi) OR (thanh do)) cua te".
• Adding a wildcard symbol may retrieve word variants: ((toc sach) or (hoc sach)) ky nang x hoi. lieu va nam thu dat ((thanh doi) OR (thanh do)) cua te*.
