• Performing a fuzzy search may retrieve terms with similar spellings: hoc thien anh - thanh ((((trung cua) OR (trung cap))) or (tuong cua)) tong cong dan toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien anh - thanh ((((trung cua) OR (trung cap))) OR (tuong cua)) tong cong dan toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien anh - thanh ((((trung cua) OR (trung cap))) or (tuong cua)) tong cong dan toan ban*".
