• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien danh - ((anh han) OR (anh bai)) cua ((nhung cong) OR (hang cong)) anh tuan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien danh - ((anh han) or (anh bai)) cua ((nhung cong) OR (hang cong)) anh tuan ban".
• Adding a wildcard symbol may retrieve word variants: hoc thien danh - ((anh han) or (anh bai)) cua ((nhung cong) OR (hang cong)) anh tuan ban*.
