• If you are trying to use Boolean operators, they must be ALL CAPS: ((((quyen tai) OR (xuyen tai))) OR (nguyen thanh)) cuc thue đe co ban ke do ke cong cong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((quyen tai) OR (xuyen tai))) or (nguyen thanh)) cuc thue đe co ban ke do ke cong cong".
• Adding a wildcard symbol may retrieve word variants: ((((quyen tai) OR (xuyen tai))) or (nguyen thanh)) cuc thue đe co ban ke do ke cong cong*.
