• If you are trying to use Boolean operators, they must be ALL CAPS: te tai ky trong ca hoi. ((hieu ve) OR (hieu van)) ((cam tuc) OR (cam tu)) va danh ve ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te tai ky trong ca hoi. ((hieu ve) or (hieu van)) ((cam tuc) OR (cam tu)) va danh ve ve triet".
• Adding a wildcard symbol may retrieve word variants: te tai ky trong ca hoi. ((hieu ve) or (hieu van)) ((cam tuc) OR (cam tu)) va danh ve ve triet*.
