• Performing a fuzzy search may retrieve terms with similar spellings: hoc thien hach - ((canh doanh) or (doanh doanh)) cua dang cong ((dan phan) OR (van phan)) dau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien hach - ((canh doanh) OR (doanh doanh)) cua dang cong ((dan phan) OR (van phan)) dau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien hach - ((canh doanh) or (doanh doanh)) cua dang cong ((dan phan) OR (van phan)) dau*".
