• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((anh tang) OR (anh nang)) va nhung cong ((hach toan) OR (thanh toan)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((anh tang) or (anh nang)) va nhung cong ((hach toan) OR (thanh toan)) ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((anh tang) or (anh nang)) va nhung cong ((hach toan) OR (thanh toan)) ban*.
