• Performing a fuzzy search may retrieve terms with similar spellings: hoa cua tinh - ((manh tran) or (canh tranh)) xuan ((khong cang) OR (thong cong)) dan phan cac~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoa cua tinh - ((manh tran) OR (canh tranh)) xuan ((khong cang) OR (thong cong)) dan phan cac.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoa cua tinh - ((manh tran) or (canh tranh)) xuan ((khong cang) OR (thong cong)) dan phan cac".
• Adding a wildcard symbol may retrieve word variants: hoa cua tinh - ((manh tran) or (canh tranh)) xuan ((khong cang) OR (thong cong)) dan phan cac*.
