• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien anh) OR (thien thanh)) - hanh tang cua trong cong van ((quang tuan) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien anh) OR (thien thanh)) - hanh tang cua trong cong van ((quang tuan) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thien anh) OR (thien thanh)) - hanh tang cua trong cong van ((quang tuan) or (toan ban))*.
