• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu tinh) or (cua tinh)) - ((ganh nang) OR (anh nang)) duy dung cong van toan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu tinh) OR (cua tinh)) - ((ganh nang) OR (anh nang)) duy dung cong van toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu tinh) or (cua tinh)) - ((ganh nang) OR (anh nang)) duy dung cong van toan tap".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu tinh) or (cua tinh)) - ((ganh nang) OR (anh nang)) duy dung cong van toan tap*.
