• Performing a fuzzy search may retrieve terms with similar spellings: te ((lai ky) OR (sai ky)) dang cay phoi. ((hieu ve) or (hieu va)) am thuc va tinh doi cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((lai ky) OR (sai ky)) dang cay phoi. ((hieu ve) OR (hieu va)) am thuc va tinh doi cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((lai ky) OR (sai ky)) dang cay phoi. ((hieu ve) or (hieu va)) am thuc va tinh doi cua viet*".
