• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thien) OR (hoc hien)) anh - hanh tang cua nhung cong van ((tuan ban) or (van ban))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thien) OR (hoc hien)) anh - hanh tang cua nhung cong van ((tuan ban) or (van ban))*.
