• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky nang x hoi. hieu ve cam ((lao va) OR (tao va)) hanh ((vai cua) OR (di cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky nang x hoi. hieu ve cam ((lao va) OR (tao va)) hanh ((vai cua) or (di cua)) triet".
• Adding a wildcard symbol may retrieve word variants: tu san ky nang x hoi. hieu ve cam ((lao va) OR (tao va)) hanh ((vai cua) or (di cua)) triet*.
