• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((anh sang) OR (((anh dang) OR (anh dung)))) cua dang trong dinh van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((anh sang) or (((anh dang) OR (anh dung)))) cua dang trong dinh van ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((anh sang) or (((anh dang) OR (anh dung)))) cua dang trong dinh van ban*.
