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