• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky ((dang xay) OR (dang van)) hoi. lieu va cac tuc ca dao hai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su xac)) ky ((dang xay) or (dang van)) hoi. lieu va cac tuc ca dao hai cua triet".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su xac)) ky ((dang xay) or (dang van)) hoi. lieu va cac tuc ca dao hai cua triet*.
