• Performing a fuzzy search may retrieve terms with similar spellings: hoc thieu xanh - thanh ((((tung cua) OR (dung cua))) or (tuong cua)) nong cong dan than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh ((((tung cua) OR (dung cua))) OR (tuong cua)) nong cong dan than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh ((((tung cua) OR (dung cua))) or (tuong cua)) nong cong dan than cau*".
