• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu tinh - ((anh hang) OR (anh hoang)) cua thong cong tan ((toan ban) OR (van ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - ((anh hang) or (anh hoang)) cua thong cong tan ((toan ban) OR (van ban))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu tinh - ((anh hang) or (anh hoang)) cua thong cong tan ((toan ban) OR (van ban))*.
