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