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