• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - ((anh tang) or (anh hoang)) cua dang trong ((mach toan) OR (hach toan)) ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - ((anh tang) or (anh hoang)) cua dang trong ((mach toan) OR (hach toan)) ban*.
