• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu sang)) - hanh trung cua nhung cong tan ((tran ban) OR (tranh ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chieu sang)) - hanh trung cua nhung cong tan ((tran ban) or (tranh ban))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chieu sang)) - hanh trung cua nhung cong tan ((tran ban) or (tranh ban))*.
