• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sang ky) OR (sang kyo)) tang ma hoi. hieu ve cac xuc va dan du ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sang ky) OR (sang kyo)) tang ma hoi. hieu ve cac xuc va dan du ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sang ky) OR (sang kyo)) tang ma hoi. hieu ve cac xuc va dan du ((cua tre) or (cuu tre))*".
