• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu tinh - ((nhan dang) OR (phan dang)) cua nhung phung manh ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu tinh - ((nhan dang) OR (phan dang)) cua nhung phung manh ((toan cau) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doc hieu tinh - ((nhan dang) OR (phan dang)) cua nhung phung manh ((toan cau) or (toan ban))*.
